According to the man files it should work but I don't even getting close to solving this issue :-/
I have maxed out logging but nothing seems to have anything to do with this.
I have tried to run "strace su - username" and on winbindd process and I can't see anything that even tries to write a krb5cc.
What part of the system should create to cc files?
Can anyone please give me a hint how I can trace this problem?

Subject: Getting no ticket cache from pam_winbind
I'm trying to get pam_winbind to create ticket cache on login if the AD is available.
Please note that this is an Ubuntu Lucid system.
When trace this with wireshark it receives a TGT ticket for the user.
The current solution is to use pam_krb5 before attempting winbind. That gives me a ticket cache.
The main problem is that if the user enters the wrong password it does two login attempts with
the same credentials (or I have to do a messy config in pam).
----- /etc/pam.d/common-auth -----
# here are the per-package modules (the "Primary" block)
auth [success=2 default=ignore] pam_unix.so nullok_secure
auth [success=1 default=ignore] pam_winbind.so krb5_auth krb5_ccache_type=FILE cached_login try_first_pass
# here's the fallback if no module succeeds
auth requisite pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
auth required pam_permit.so
# and here are more per-package modules (the "Additional" block)
# end of pam-auth-update config
auth [default=done] pam_afs_session.so
