From: Richard Sharp on
I am running an Ubuntu 9.04 machine with kernel 2.6.28-16-server,
Samba v3.3.2 that uses winbind for authentication of users.

My log files are littered with messages like these every time a user
remotely mounts their home directory:

Apr 5 07:12:40 csfile smbd[15517]: pam_unix(samba:session): session

Everything seems to work on the user end but I don't completely know
what I'm doing and I'm afraid I've misconfigured something. I've
included my smb.conf file below. Any help is appreciated.

Thank you,
Rich
