Urgent help request! was Re: how do you get something to run when a user logs on?

[john]

Hi Vu,

We use win2k3 for authentication as well via winbind. We used to host
student files on a windows server and I believe we used the pam_mount
module to mount the shares on a per user basis
  http://pam-mount.sourceforge.net/

Last year we moved the student files over to Linux and we are happy
with the results. Since we're in a mixed environment we can share
files with WindowsXP users via samba, with our LTSP clients via NFS
and even allow remote access via sftp.

I DO wish that /etc/profile would still work as it used to. I am sure
there are good reasons for moving to an image based approach (if
that's the right way to describe it) but I don't like the fact that it
breaks the way *nix has worked for 20 years or so.
