Fedora Update Notification

---------------------------------------------------------------------
 
Name        : pam_krb5
Version     : 2.0.5
Release     : 1
Summary     : A Pluggable Authentication Module for Kerberos 5.
Description :
This is pam_krb5, a pluggable authentication module that can be used with
Linux-PAM and Kerberos 5. This module supports password checking, ticket
creation, and optional TGT verification and conversion to Kerberos IV tickets.
The included pam_krb5afs module also gets AFS tokens if so configured.
 
---------------------------------------------------------------------
Update Information:
 
The version of pam_krb5 included in Fedora Core 1 did not honor the
ticket_lifetime setting in /etc/krb5.conf's [appdefaults] section, in
the "pam" subsection.  The default renewable lifetime set in this
configuration file is 10 hours.  The default ticket lifetime used in
libkrb5 is 24 hours.

When answering a request for initial credentials which specifies
these lifetimes, some KDC implementations will reply with initial
credentials with a renewable lifetime increased to match the ticket
lifetime.  This modification to the response is treated as an error
by libkrb5, and authentication fails when it would otherwise succeed.

The updated version of pam_krb5 now honors the ticket_lifetime
setting, and the configured default ticket lifetime (10 hours) does
not trigger this error condition.

 the RPM changelog didn't because it's in the docdir ChangeLog.]

Shouldn't that be "Fedora Test Update Notification"?

With all these inconsistencies in message subject and body, it gets
a bit troublesome to keep the local filtering up-to-date. First
I've tried to adapt to the changing subject line. Now the message
body keeps changing to. The regexp is getting longer.

So far I resorted to filtering over a message header.  If it is
"To: fedora-test-list...." then this is "Fedora Test ...." and
URLs will have "testing" in them even if a posting itself says
otherwise.  For a time beeing it works. :-)

Yeah.  The message is generated by a script, but its output currently
needs to be modified for tests, and I missed that spot.
