-Unpacking the Source Distribution
----------------------------------
+Copyright and Other Notices
+---------------------------
-The source distribution of Kerberos 5 comes in a gzipped tarfile,
-krb5-1.3.tar.gz. Instructions on how to extract the entire
-distribution follow.
+Copyright (C) 1985-2010 by the Massachusetts Institute of Technology
+and its contributors. All rights reserved.
-If you have the GNU tar program and gzip installed, you can simply do:
-
- gtar zxpf krb5-1.3.tar.gz
-
-If you don't have GNU tar, you will need to get the FSF gzip
-distribution and use gzcat:
-
- gzcat krb5-1.3.tar.gz | tar xpf -
-
-Both of these methods will extract the sources into krb5-1.3/src and
-the documentation into krb5-1.3/doc.
+Please see the file named NOTICE for additional notices.
Building and Installing Kerberos 5
----------------------------------
and logging in as "guest" with password "guest".
-Notes, Major Changes, and Known Bugs for 1.3
---------------------------------------------
-
-* We now install the compile_et program, so other packages can use the
- installed com_err library with their own error tables. (If you use
- our com_err code, that is; see below.)
-
-* The header files we install now assume ANSI/ISO C ('89, not '99).
- We have stopped testing on SunOS 4, even with gcc. Some of our code
- now has C89-based assumptions, like free(NULL) being well defined,
- that will probably frustrate any attempts to run this code under SunOS
- 4 or other pre-C89 systems.
-
-* Some new code, bug fixes, and cleanup for IPv6 support. [[TODO:
- Insert list of (non-)supporting programs and libraries here.]]
-
-* We have upgraded to autoconf 2.52 (or later), and the syntax for
- specifying certain configuration options have changed. For example,
- autoconf 2.52 configure scripts let you specify command-line options
- like "configure CC=/some/path/foo-cc", so we have removed some of
- our old options like --with-cc in favor of this approach.
-
-* The client libraries can now use TCP to connect to the KDC. This
- may be necessary when talking to Microsoft KDCs (domain controllers),
- if they issue you tickets with lots of PAC data.
-
-* If you have versions of the com_err, ss, or Berkeley DB packages
- installed locally, you can use the --with-system-et,
- --with-system-ss, and --with-system-db configure options to use them
- rather than using the versions supplied here. Note that the
- interfaces are assumed to be similar to those we supply; in
- particular, some older, divergent versions of the com_err library
- may not work with the krb5 sources. Many configure-time variables
- can be used to help the compiler and linker find the installed
- packages; see the build documentation for details.
-

- This software is provided 'as is' with no explcit or implied warranties
- in respect of any properties, including, but not limited to, correctness
- and fitness for purpose.
+The Data Encryption Standard (DES) is widely recognized as weak. The
+krb5-1.7 release contains measures to encourage sites to migrate away
+from using single-DES cryptosystems. Among these is a configuration
+variable that enables "weak" enctypes, which defaults to "false"
+beginning with krb5-1.8.
