Description Stephan Wiesand 2006-11-21 03:39:26 EST

Description of problem:
We're using Kerberos 5 for authentication (and AFS homed directories, if it
matters). With the current pam/krb5 configuration on EL5 beta2, the following
all work as expected:
 - login (gdm)
 - login (console)
 - login (ssh, password)
 - login (ssh, gssapi)
 - kinit, aklog
 - kscreensaver (even does the right thing - refreshs my credentials)

However, gnome-screensaver fails to unlock the screen. Having turned on
debugging for the pam_krb5afs module, I see a success message in the log
for every unlock attempt:

gnome-screensaver-dialog: pam_krb5[4638]: authentication succeeds for ...

On x86_64 only, I see in addition:

kernel: gnome-screensav[8260]: segfault at 0000003456a26730 rip 0000003456a26730
rsp 0000000040a000b8 error 14

On x86, it fails silently.

Accounts with a local password don't have this problem

Version-Release number of selected component (if applicable):

gnome-screensaver-2.16.1-2.el5.x86_64
gnome-screensaver-2.16.1-2.el5.i386

How reproducible:
100%

Hi, does

 rpm -e pkinit-nss  

work around the problem for you?

Comment 2 Stephan Wiesand 2006-11-22 00:55:00 EST

Hi, yes it does. Unlocking the screen works, no more segfaults.
