Comment 2 Marcela Mašláňová 2007-12-07 14:16:19 UTC

I'm sorry, that's works for me. 
$ rpm -q at

$ getenforce

$ at
Garbled time

Could you please attach back-trace with installed at-debuginfo?

Comment 3 Aurelien Bompard 2007-12-07 15:35:49 UTC

I've run at through gdb, and it says:

PAM authentication failure: Authentication failure
You do not have permission to use at.

Program exited with code 01.
(gdb) bt
No stack.

I've looked at my PAM authentication files, and if I comment out the pam_mount
entry in system-auth, at goes back to normal.
No idea why it blocked at only though.

Reassigning to pam_mount, if the maintainer has any idea about that...

Comment 4 Marcela Mašláňová 2007-12-10 09:52:27 UTC

I don't think there is problem with pam_mount, but I can CC maintainer. 

In _at_ were incorrectly closed parts with PAM authentication. If you want, you
can test it from here http://mmaslano.fedorapeople.org/at/ Maybe it helps. Could
you attach the part of your log from /var/log/audit/audit.log, which mentioned
unsuccessful _at_ job?

Please don't move bug into modified state, that's for solved bugs.

It still segfaults with 3.1.10-20

Nothing about that in /var/log/audit/audit.log, but I can find interesting lines
in /var/log/secure : 

Dec 10 11:51:51 localhost at: pam_unix(atd:session): session opened for user
abompard by (uid=0)
Dec 10 11:51:51 localhost at: pam_mount(pam_mount.c:413) error trying to
retrieve authtok from auth code

Hope this helps.

Sorry about that, I didn't know.

Comment 6 Marcela Mašláňová 2007-12-12 10:58:31 UTC

Please could you also attach backtrace of at?

Comment 7 Marcela Mašláňová 2008-01-28 09:04:32 UTC

I'm closing it. If the problem persist please free to reopen it.
