pam_listfile for session?

[Robert Penz]

Hi! 

I'm using following to mount some samba shares after success authentication 
against the PDC. 

auth       optional   pam_mount.so use_first_pass
session    optional   pam_mount.so use_first_pass 

The problem now is that I get following if I login as root or an local user. 

pam_mount: error trying to retrieve authtok from auth code
pam_mount: Conversation error
pam_mount: error trying to read password 

Which is ofcourse correct and it still works, but doesn't look good - 
specially if I've some scripts which login via ssh and report an error if 
they got anything in stdout/stderr. I'm now searching for something which 
prevents the session line to be excuted for local users. First I thought at 
something like 

session     sufficient pam_listfile.so item=user sense=allow 
file=/etc/localusers onerr=success 

but pam_listfile does not support the session management. Has anyone an 
other idea? thx.
