Description Josh Bressers 2005-09-02 17:49:17 UTC 
destroy credentials if krb5_kuserok() call fails. Stops credentials being
delegated to users who are not authorised for GSSAPIAuthentication when
GSSAPIDeletegateCredentials=yes and another authentication mechanism succeeds;
Comment 1 Josh Bressers 2005-09-02 17:50:08 UTC 
This issue may also affect RHEL3 and RHEL2.1 (I've not verified it)

Patch from upstream
Comment 3 Josh Bressers 2005-09-05 14:12:34 UTC 
This issue does not affect RHEL3 and RHEL2.1 as they do not contain GSSAPI
authentication.
