At last, the 0.2 version of pam_mount is shipping! This PAM module has been useful since the very first version (0.01) but this is the first "decent" version, with an RPM etc.
This module can mount remote volumes at login time, reusing the password the user has just typed. It can be pretty useful in environments where there are Windows NT and Netware private volumes that any user needs to have access during a Unix session.
Tarball and RPMs can be found here.
