Description Nicolas Mailhot 2004-10-22 08:10:03 UTC
On a rawhide system that uses krb for passwords and ldap for group
info  login does not work wirh pam 0.77-65

(logs show krb5 passwd works, id on the user works for root, but login
fails with "can not retrieve auth info")

Reverting to FC2 pam+authconfig fixes the problem

Comment 1 Tomas Mraz 2004-10-22 08:28:32 UTC
Could you please try pam+authconfig from FC3test1 and FC3test2?

Comment 2 Nicolas Mailhot 2004-10-22 08:43:15 UTC
Won't have the time to do it before monday;(

Though the rawhide box is regularly synched, and worked two days ago,
to I suppose the breakage is fairly recent and the FC3Tests should all

Comment 3 Tomas Mraz 2004-10-22 09:48:31 UTC
Now I know the cause - it happened in pam-0.77-58

Comment 7 Nicolas Mailhot 2004-10-25 10:23:58 UTC
As I suspected the FC3T3 login stack works. So pam-0.77-58 is not the

Comment 8 Tomas Mraz 2004-10-25 10:53:04 UTC
I'm sorry but I cannot reproduce it here. (I've setup krb5
authentication with ldap account info and I can successfully log in
using that configuration with users which aren't or are in /etc/passwd).

And if I look at the changes between pam-0.77-60 and pam-0.77-65 there
were virtually no changes which could affect this.

Comment 9 Nicolas Mailhot 2004-10-25 11:36:02 UTC
Well there is an authconfig version change too since FC3T3 so the bug
might be there not in pam.

Anyway the problem is 100% reproductible. Just tell me what tests you
want me to run and I'll do them (when I have access to the system ie
during french business hours)

Login failure messages with rawhide pam :

Comment 11 Tomas Mraz 2004-10-25 12:29:03 UTC
Please attach your /etc/pam.d/system-auth and login files.

Also can you add debug option to the pam_stack module calls in the
/etc/pam.d/login and add line:
*.=debug               /var/log/debug
to the /etc/syslog.conf and rerun the test with the failing packages
and attach the debug log file?

Thank you.

Comment 15 Nicolas Mailhot 2004-10-27 08:48:01 UTC
After testing your rpms pam-0.77-62 works, pam-0.77-63 and later - not

Comment 16 Tomas Mraz 2004-10-27 09:17:32 UTC
So I fixed a bug and it revealed another bug (this time in the pam
configuration) - could you reupgrade to pam-0.77-65 and add
broken_shadow option to the account line of pam_unix module?
If it helps I'll change authconfig to add this option when using
configuration like yours.
Thank you for the testing.

(Nicolas.Mailhot@laPoste.net)  on 2004-10-27 06:26 -------

account     required      /lib/security/$ISA/pam_unix.so broken_shadow
the rawhide login stack works. Thanks !

(not closing since the packages are not fixed yet)

Comment 20 Tomas Mraz 2004-12-08 08:44:29 UTC
This is fixed in FC3 and RHEL4 packages.
