Subject: Added new extra flags argument to the call to krb5_recvauth()
X-Git-Tag: krb5-1.0-beta3~116
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=76026a80744c64dced2d4c80618ce4d874217ac9;p=krb5.git

Added new extra flags argument to the call to krb5_recvauth()

The service name is automatically determined using krb5_sname_to_principal().
If an argument is specified, it is taken to be the port number on which
the sample server should run (instead of being run out of inetd).
