Title: Proper use of pam_krb5 within system-auth to achieve SSO

Running FC2

·       kernel 2.6.5-1.358
·       krb5-workstation/libs/devel-1.3.3-1
·       pam-krb5-2.0.10-1

I would like to achieve a single-sign on, authenticating against AD (Win Server 2003) and retrieving a Kerberos ticket, and pulling down user groups.  I have the proper config files(Kerberos & Samba), but the error seems to be in my system-auth module. 

The login bombs in 2 places on the Linux side

1.      After entering username
a.      pam_krb5: error resolving user name superman to uid/gid pair
b.      pam_krb5: error getting information about superman
2.      After entering password
a.      gdm-binary: Couldnt set acct. mgmt. for superman

On the Win2003 side, superman does authenticate via winbind, but there exists no log showing a Kerberos request.

Also: I can retrieve tickets using kinit and superman/password

        getent passwd/group retrieves the users and groups on the AD server

        wbinfo u/-g retrieves the AD groups

Any ideas?

I appreciate any help/direction,

Here is my pam.d/system-auth file:

*This is a mixture of what the authentication applet creates and suggestions Ive found online.  Some of those suggestions have stated that the login modules needs to manipulated, but since it calls the system-auth module, I dont see why it would be necessary, if it is please explain.
