"Roaming profiles" style system... suggestions?

[Madison Kelly]

Hi all,

   I am trying to set up my first all-Linux network. Until now most of 
my networks have been based on MS clients or, more often, networks where 
"normal" communication was using web-based front ends.

   As it stands I am currently planning to have the server connect to 
each client at night using 'rsync' and copying any deltas over to the 
server before running a backup. What I would really like to do though is 
have a setup similar to MS' "roaming profiles" like I used to use over 
Samba. I know that I could use an NFS share as the user's home directory 
which is mounted at boot. That though would limit the system to one user 
  to a given machine.

   Is there a way (google hasn't helped yet) to have a script run when a 
user enters their name and password? This way, I hope, I could write a 
script that would not mount anything off NFS until the user logs in and 
then mount the appropriate NFS share when the user validates him or 
herself.

   Is there any how-tos or other helpful information someone could point 
me to? It would be a real help! Thank you!

Madison
