libpam-smbpass 2:3.5.11~dfsg-1ubuntu2 (powerpc binary) in ubuntu oneiric

 This is a module for PAM that enables a system administrator to migrate
 user passwords from the Unix password database to the SMB password
 database as used by Samba, and to subsequently keep the two databases in
 sync. Unlike other solutions, it does this without needing users to log
 in to Samba using cleartext passwords, or requiring them to change their
 existing passwords.
