- OpenVision Technologies, Inc. has donated this Kerberos
- Administration system to MIT for inclusion in the standard
- Kerberos 5 distribution. This donation underscores our
- commitment to continuing Kerberos technology development
- and our gratitude for the valuable work which has been
- performed by MIT and the Kerberos community.
+The source distribution of Kerberos 5 comes in three gzipped tarfiles,
+krb5-1.0.src.tar.gz, krb5-1.0.doc.tar.gz, and krb5-1.0.crypto.tar.gz.
+The krb5-1.0.doc.tar.gz contains the doc/ directory and this README
+file. The krb5-1.0.src.tar.gz contains the src/ directory and this
+README file, except for the crypto library sources, which are in
+krb5-1.0.crypto.tar.gz.
+
+Instruction on how to extract the entire distribution follow. These
+directions assume that you want to extract into a directory called
+DIST.
+
+If you have the GNU tar program and gzip installed, you can simply do:
+
+ mkdir DIST
+ cd DIST
+ gtar zxpf krb5-1.0.src.tar.gz
+ gtar zxpf krb5-1.0.crypto.tar.gz
+ gtar zxpf krb5-1.0.doc.tar.gz
+If you don't have GNU tar, you will need to get the FSF gzip
+distribution and use gzcat:
+ mkdir DIST
+ cd DIST
+ gzcat krb5-1.0.src.tar.gz | tar xpf -
+ gzcat krb5-1.0.crypto.tar.gz | tar xpf -
+ gzcat krb5-1.0.doc.tar.gz | tar xpf -
-Now, with that out of the way, let me point you to a few things:
+Both of these methods will extract the sources into DIST/krb5-1.0/src
+and the documentation into DIST/krb5-1.0/doc.
+
+Unpacking the Binary Distribution
+---------------------------------
+
+Binary distributions of Kerberos V5 are provided merely as convenience
+to those people who wish to try out Kerberos V5 without needing to do
+a full compile of Kerberos.
+
+MIT and the MIT Kerberos V5 development team make no guarantees that
+we will continue to supply binary distributions for future releases of
+Kerberos V5, or for any operating system/platform in particular.
+These binary distributions have been prepared by members of the MIT
+Kerberos V5 development team, or by volunteers who have graciously
+agreed to test the pre-release snapshot. Each binary build is PGP
+signed by the person who prepared the binary distribution for that
+particular platform.
+
+While the binary distribution is *supposed* to correspond exactly to
+the 1.0 Kerberos V5 source release, you have no way of knowing whether
+the person who prepared the binary release might have inserted a
+trojan horse, or a trapdoor. For all you know, the binary
+distribution might be mailing all of your Kerberos keys to
+kremvax!boris. (The same is true for the source distribution, but at
+least you can audit the code yourself!)
+
+For this reason, if you are planning on using Kerberos V5 in
+production, we strongly suggest that you obtain the source
+distribution and compile it from source yourself.
+
+The binary distributions have been compiled so that they will install
+in /usr/local. To install, su to root and and type the command:
+
+ cd /usr/local
+ gunzip < /tmp/krb5-1.0.<platform>.tar.gz | tar xvf -
+
+
+Building and Installing Kerberos 5
+----------------------------------
The first file you should look at is doc/install.ps; it contains the
notes for building and installing Kerberos 5. The info file
respectively. They are also available as info files
kerberos-admin.info and krb5-user.info, respectively.
->> <<
->> Please report any problems/bugs/comments to 'krb5-bugs@mit.edu' <<
->> <<
+Reporting Bugs
+--------------
+
+Please report any problems/bugs/comments using the krb5-send-pr
+program. The krb5-send-pr program will be installed in the sbin
+directory once you have successfully compiled and installed Kerberos
+V5 (or if you have installed one of our binary distributions).
+
+If you are not able to use krb5-send-pr because you haven't been able
+compile and install Kerberos V5 on any platform, you may send mail to
+krb5-bugs@mit.edu.
+
+Notes and Major Changes
+-----------------------
+
+* We are now using the GNATS system to track bug reports for Kerberos
+V5. It is therefore helpful for people to use the krb5-send-pr
+program when reporting bugs. The old interface of sending mail to
+krb5-bugs@mit.edu will still work; however, bug reports sent in this
+fashion may experience a delay in being processed.
+
+* The default keytab name has changed from /etc/v5srvtab to
+/etc/krb5.keytab.
+
+* login.krb5 no longer defaults to getting krb4 tickets.
+
+* The Windows (win16) DLL, LIBKRB5.DLL, has been renamed to
+KRB5_16.DLL. This change was necessary to distinguish it from the
+win32 version, which will be named KRB5_32.DLL. Note that the
+GSSAPI.DLL file has not been renamed, because this name was specified
+in a draft standard for the Windows 16 GSSAPI bindings. (The 32-bit
+version of the GSSAPI DLL will be named GSSAPI32.DLL.)
+
+* The directory structure used for installations has changed. In
+particular, files previously located in $prefix/lib/krb5kdc are now
+normally located in $sysconfdir/krb5kdc. With the normal configure
+options, this means the KDC database goes in /usr/local/var/krb5kdc by
+default. If you wish to have the old behavior, then you would use a
+configure line like the following:
+
+ configure --prefix=/usr/local --sysconfdir=/usr/local/lib
+* kshd has been modified to accept krb4 encrypted rcp connections; for
+this to work, the v4rcp program must be in the bin directory.
+* The gssrpc library has symbol collisions with the rpc library in
+some of the libcs in certain operating systems without shared
+libraries, notably some ports of NetBSD and MkLinux. For those
+platforms which have rpc in libc and also contain NIS in libc,
+compiling with static libraries will not work because of this
+conflict. NetBSD users can either upgrade to the current tree, which
+includes shared libraries for more ports, choose not to build kadmind
+or kadmin, or recompile NetBSD without NIS support. MkLinux users
+must either recompile without NIS or not build the administration
+system.

+The @code{krb5.conf} file contains Kerberos configuration information,
+including the locations of KDCs and admin servers for the Kerberos
+realms of interest, defaults for the current realm and for Kerberos
+applications, and mappings of hostnames onto Kerberos realms. Normally,
+you should install your @code{krb5.conf} file in the directory
+@code{/etc}. You can override the default location by setting the
+environment variable @samp{KRB5_CONFIG}.
+
+The @code{krb5.conf} file is set up in the style of a Windows INI file.
+Sections are headed by the section name, in square brackets. Each
+section may contain zero or more relations, of the form:

+
+The @code{krb5.conf} file may contain any or all of the following seven
+sections:
+
+@table @b
+@itemx libdefaults
+Contains default values used by the Kerberos V5 library.
+
+@itemx appdefaults
+Contains default values used by Kerberos V5 applications.
+
+@itemx realms
+Contains subsections keyed by Kerberos realm names. Each subsection
+describes realm-specific information, including where to find the
+Kerberos servers for that realm.
+
+@itemx domain_realm
+Contains relations which map domain names and subdomains onto Kerberos
+realm names. This is used by programs to determine what realm a host
+should be in, given its fully qualified domain name.
+
+@itemx logging
+Contains relations which determine how Kerberos programs are to perform
+logging.
+

+
+@itemx default_tgs_enctypes
+Identifies the supported list of session key encryption types that

+type is "des-cbc-crc".
+
+@itemx clockskew
+Sets the maximum allowable amount of clockskew in seconds that the
+library will tolerate before assuming that a Kerberos message is
+invalid. The default value is 300 seconds, or five minutes.
+
+@itemx checksum_type
+Used for compatability with DCE security servers which do not support
+the default CKSUMTYPE_RSA_MD5 used by this version of Kerberos. A value

+CKSUMTYPE_RSA_MD4 instead. This applies to DCE 1.1 and earlier.
+
+@itemx ccache_type
+Use this parameter on systems which are DCE clients, to specify the type

+@subsection [domain_realm]
+
+The [domain_realm] section provides a translation from a domain name or

+a domain name, where domain names are indicated by a prefix of a period
+(@samp{.}). The value of the relation is the Kerberos realm name for
+that particular host or domain. Host names and domain names should be
+in lower case.
+
+If no translation entry applies, the host's realm is considered to be

+@node logging, capaths, domain_realm, krb5.conf
+@subsection [logging]
+The [logging] section indicates how a particular entity is to perform
+its logging. The relations in this section assign one or more values to
+the entity name. Currently, the following entities are used:
+
+@table @b
+@itemx admin_server
+These entries specify how the administrative server
+is to perform its logging.
+
+@itemx default
+These entries specify how to perform logging in the
+absence of explicit specifications otherwise.
+@end table
+
+Values are of the following forms:
+
+@table @b
+@itemx FILE=<filename>
+
+@itemx FILE:<filename>
+This value causes the entity's logging messages to go to the specified
+file. If the @samp{=} form is used, the file is overwritten. If the
+@samp{:} form is used, the file is appended to.
+
+@itemx STDERR
+This value causes the entity's logging messages to go to its standard
+error stream.
+
+@itemx CONSOLE
+This value causes the entity's logging messages to go to the console, if
+the system supports it.
+
+@itemx DEVICE=<devicename>
+This causes the entity's logging messages to go to the specified device.
+
+@itemx SYSLOG[:<severity>[:<facility>]]
+This causes the entity's logging messages to go to the system log.
+
+The @dfn{severity} argument specifies the default severity of system log
+messages. This may be any of the following severities supported by the
+@code{syslog(3)} call, minus the LOG_ prefix: LOG_EMERG, LOG_ALERT,
+LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, and LOG_DEBUG.
+For example, a value of @samp{CRIT} would specify LOG_CRIT severity.
+
+The facility argument specifies the facility under which the messages
+are logged. This may be any of the following facilities supported by
+the syslog(3) call minus the LOG_ prefix: LOG_KERN, LOG_USER, LOG_MAIL,
+LOG_DAEMON, LOG_AUTH, LOG_LPR, LOG_NEWS, LOG_UUCP, LOG_CRON, and
+LOG_LOCAL0 through LOG_LOCAL7.
+
+If no severity is specified, the default is ERR. If no facility is
+specified, the default is AUTH.
+@end table
+
+In the following example, the logging messages from the KDC will go to
+the console and to the system log under the facility LOG_DAEMON with
+default severity of LOG_INFO; and the logging messages from the
+administrative server will be appended to the file /var/adm/kadmin.log
+and sent to the device /dev/tty04.

+@subsection [capaths]
+
+In order to perform direct (non-hierarchical) cross-realm
+authentication, a database is needed to construct the authentication
+paths between the realms. This section defines that database.
+
+A client will use this section to find the authentication path between
+its realm and the realm of the server. The server will use this section
+to verify the authentication path used be the client, by checking the
+transited field of the received ticket.
+
+There is a tag for each participating realm, and each tag has subtags
+for each of the realms. The value of the subtags is an intermediate
+realm which may participate in the cross-realm authentication. The
+subtags may be repeated if there is more then one intermediate realm. A
+value of "." means that the two realms share keys directly, and no
+intermediate realms should be allowd to participate.
+
+There are n**2 possible entries in this table, but only those entries
+which will be needed on the client or the server need to be present.
+The client needs a tag for its local realm, with subtags for all the
+realms of servers it will need to authenticate with. A server needs a
+tag for each realm of the clients it will serve.
+
+For example, ANL.GOV, PNL.GOV, and NERSC.GOV all wish to use the ES.NET
+realm as an intermediate realm. ANL has a sub realm of TEST.ANL.GOV
+which will authenticate with NERSC.GOV but not PNL.GOV. The [capath]
+section for ANL.GOV systems would look like this:
+
+@smallexample
+@group
+[capaths]
+ ANL.GOV = @{
+ TEST.ANL.GOV = .
+ PNL.GOV = ES.NET
+ NERSC.GOV = ES.NET

+ @}
+ TEST.ANL.GOV = @{
+ ANL.GOV = .
+ @}
+ PNL.GOV = @{
+ ANL.GOV = ES.NET
+ @}
+ NERSC.GOV = @{
+ ANL.GOV = ES.NET
+ @}
+ ES.NET = @{
+ ANL.GOV = .
+ @}
+@end group
+@end smallexample
+
+The [capath] section of the configuration file used on NERSC.GOV systems
+would look like this:
+
+@smallexample
+@group
+[capaths]
+ NERSC.GOV = @{
+ ANL.GOV = ES.NET
+ TEST.ANL.GOV = ES.NET
+ TEST.ANL.GOV = ANL.GOV
+ PNL.GOV = ES.NET
+ ES.NET = .
+ @}
+ ANL.GOV = @{
+ NERSC.GOV = ES.NET
+ @}
+ PNL.GOV = @{
+ NERSC.GOV = ES.NET
+ @}
+ ES.NET = @{

+ TEST.ANL.GOV = @{
+ NERSC.GOV = ANL.GOV
+ NERSC.GOV = ES.NET
+ @}
+@end group
+@end smallexample
+
+In the above examples, the ordering is not important, except when the
+same subtag name is used more then once. The client will use this to
+determing the path. (It is not important to the server, since the
+transited field is not sorted.)
+
+This feature is not currently supported by DCE. DCE security servers
+can be used with Kerberized clients and servers, but versions prior to
+DCE 1.1 did not fill in the transited field, and should be used with

will cause the testsuite to exit with a non-zero exit status which
@samp{make} will consider a failure of the testing process. Do not worry

+@subsection The KADM5 Tests
+
+Regression tests for the KADM5 system, including the GSS-RPC, KADM5
+client and server libraries, and kpasswd, are also included in this
+release. Each set of KADM5 tests is contained in a sub-directory called
+@code{unit-test} directly below the system being tested. For example,
+lib/rpc/unit-test contains the tests for GSS-RPC. The tests are all
+based on DejaGnu (but they are not actually called part of "The DejaGnu
+tests," whose naming predates the inclusion of the KADM5 system). In
+addition, they require the Tool Command Language (TCL) header files and
+libraries to be available during compilation and some of the tests also
+require Perl in order to operate. If all of these resources are not
+available during configuration, the KADM5 tests will not run. The TCL
+installation directory can be specified with the @code{--with-tcl}
+configure option (see @xref{Options to Configure}). The runtest and
+perl programs must be in the current execution path.
+
+If you install DejaGnu, TCL, or Perl after configuring and building
+Kerberos and then want to run the KADM5 tests, you will need to
+re-configure the tree and run @code{make} at the top level again to make
+sure all the proper programs are built. To save time, you actually only
+need to reconfigure and build in the directories src/kadmin/testing,
+src/lib/rpc, src/lib/kadm5, and src/kpasswd.

@section Options to Configure
Provides help to configure. This will list the set of commonly used
options for building Kerberos.
-@item --prefix=DIR
+@item --prefix=PREFIX
By default, Kerberos will install the package's files rooted at
`/usr/local' as in `/usr/local/bin', `/usr/local/sbin', etc. If you
-desire a different location use this option.
+desire a different location, use this option.
-@item --exec-prefix=DIR
+@item --exec-prefix=EXECPREFIX
This option allows one to separate the architecture independent programs
from the configuration files and manual pages.
+@item --localstatedir=LOCALSTATEDIR
+
+This option sets the directory for locally modifiable single-machine
+data. In Kerberos, this mostly is useful for setting a location for the
+KDC data files, as they will be installed in
+@code{LOCALSTATEDIR/krb5kdc}, which is by default
+@code{PREFIX/var/krb5kdc}.
+
@item --with-cc=COMPILER
Use @code{COMPILER} as the C compiler.
@item --with-krb4=KRB4DIR
-This option enables Kerberos V4 backwards compatibility. The directory
-specified by @code{KRB4DIR} specifies where the V4 header files should
-be found (@file{/KRB4DIR/include}) as well as where the V4 Kerberos
-library should be found (@file{/KRB4DIR/lib}).
+This option enables Kerberos V4 backwards compatibility using a

+be found (@file{KRB4DIR/lib}).
@item --without-krb4
modified (and thus needing to be locked) frequently. Please note that
the implementors do not regularly test this feature.
-@item --with-kdb-db=database
-
-The configuration process will try to determine a working set of
-libraries required to implement the Kerberos database. Configure will
-look for interfaces that use or emulate a @samp{ndbm} or @samp{dbm}
-library. Failing that, a build in copy of the Berkeley DB code will be
-used. You may decide to compile a different interface than the default
-by specifying one of "ndbm", "dbm", or "db".
+@item --with-tcl=TCLPATH
-An important note on platforms where the @samp{ndbm} implementation is
-based on @sc{GDBM} (such as the Linux Slackware distribution). @sc{GDBM}
-has its own built in file locking which prevents simultaneous access to
-the database from two separate processes in which one wants to modify
-the database while the otherone only wants to read. (i.e. the KDC and
-administrative servers). In this case, you will need to specify the use
-of the Berkeley DB.
+Some of the unit-tests in the build tree rely upon using a program in
+Tcl. The directory specified by @code{TCLPATH} specifies where the Tcl
+header file (@file{TCLPATH/include/tcl.h} as well as where the Tcl
+library should be found (@file{TCLPATH/lib}).
@end table
The profile file format is no longer the same format as Kerberos V4's

.SH DESCRIPTION
.I Klogind
is the server for the
window size of the terminal is requested from the client, and window
size changes from the client are propagated to the pseudo terminal.
+.PP
+.I Klogind
+supports the following options to control the form of the hostname
+passed to login(1):
+
+.TP
+\fB\-w \fP[\fBip\fP|\fImaxhostlen\fP[\fB,\fP[\fBno\fP]\fBstriplocal\fP]]
+Controls the form of the remote hostname passed to login(1).
+Specifying \fBip\fP results in the numeric IP address always being
+passed to login(1). Specifying a number, \fImaxhostlen\fP, sets the
+maximum length of the hostname passed to login(1) before it will be
+passed as a numeric IP address. If \fImaxhostlen\fP is 0, then the
+system default, as determined by the utmp or utmpx structures, is
+used. The \fBnostriplocal\fP and \fBstriplocal\fP options, which must
+be preceded by a comma, control whether or not the local host domain
+is stripped from the remote hostname. By default, the equivalent of
+\fBstriplocal\fP is in effect.
+
.PP
.I Klogind
supports three options which are used for testing

.SH DESCRIPTION
.B Ftpd
is the
.I srvtab
file to use. The default value is normally
.IR /etc/krb-srvtab .
+.TP
+\fB\-w \fP[\fBip\fP|\fImaxhostlen\fP[\fB,\fP[\fBno\fP]\fBstriplocal\fP]]
+Controls the form of the remote hostname passed to login(1).
+Specifying \fBip\fP results in the numeric IP address always being
+passed to login(1). Specifying a number, \fImaxhostlen\fP, sets the
+maximum length of the hostname passed to login(1) before it will be
+passed as a numeric IP address. If \fImaxhostlen\fP is 0, then the
+system default, as determined by the utmp or utmpx structures, is
+used. The \fBnostriplocal\fP and \fBstriplocal\fP options, which must
+be preceded by a comma, control whether or not the local host domain
+is stripped from the remote hostname. By default, the equivalent of
+\fBstriplocal\fP is in effect.

The ftp server currently supports the following ftp requests; case is
not distinguished.

+.SH DESCRIPTION
The
.B telnetd
command is a server which supports the
.IR gethostbyaddr (3)
routine.
.TP
+.B \-w \fP[\fBip\fP|\fImaxhostlen\fP[\fB,\fP[\fBno\fP]\fBstriplocal\fP]]
+Controls the form of the remote hostname passed to login(1).
+Specifying \fBip\fP results in the numeric IP address always being
+passed to login(1). Specifying a number, \fImaxhostlen\fP, sets the
+maximum length of the hostname passed to login(1) before it will be
+passed as a numeric IP address. If \fImaxhostlen\fP is 0, then the
+system default, as determined by the utmp or utmpx structures, is
+used. The \fBnostriplocal\fP and \fBstriplocal\fP options, which must
+be preceded by a comma, control whether or not the local host domain
+is stripped from the remote hostname. By default, the equivalent of
+\fBstriplocal\fP is in effect.
+.TP
\fB\-X\fP \fIauthtype\fP
This option is only valid if

+ * gssapi_krb5.c: Rearrange OID's so that the V1V2 mechanism set

+ preferred).
+
+ * import_sec_context.c (krb5_gss_convert_static_mech_oid): Make

+ with a namespace compliant name, since init_sec_context()
+ needs to be able to use this function.
+
+ * indicate_mechs.c (krb5_gss_indicate_mechs): Return the both

+
+ * init_sec_context.c (krb5_gss_init_sec_context): Make
+ ctx->mech_used use a static OID, since it is returned by
+ gss_inquire_context which must return a static OID.
+
+ * wrap_size_limit.c (krb5_gss_wrap_size_limit): Fix bug where we
+ would overestimate the size of the allowable input message
+ by one byte, because we weren't passing the right estimate
+ of the wrapped data to g_token_size().
+

+
+ * import_sec_context.c: Fix up the OID of the mechanism in the

+
+ * wrap_size_limit.c (krb5_gss_wrap_size_limit): Fix to round down

+ * [pullup from trunk]
+ *
+ * Revision 1.43 1997/10/21 18:33:55 epeisach
+ * Fix to not lose entries in the chain linked client list.
+ *
+ * A pointer was not being updated resulting in the situation where
+ * random clients would sudenly fail with a misc. rpc. error as the client
+ * handle could not be found. The scenario required three active clients
+ * to trigger the problem.
+ *
+ * Revision 1.42 1996/12/04 17:47:18 bjaspan
+ * * Various changes to allow channel bindings to work with both UDP
+ * and TCP cleanly [krb5-libs/180]:
+ *
+ * * auth_gssapi.c: remove the special-case exception to channel
+ * bindings failure added in the previous revision, since we now
+ * solve the problem by making channel bindings not fail
+ *
+ * * clnt_udp.c: use a connected socket so that the client can
+ * determine its own source address with getsockname
+ *

+
+ * update_wtmp.c: Don't use updwtmpx() even if it exists for glibc
+ 2.1, since it's the same as updwtmp(), and glibc doesn't
