Depends on which version you run there are two solutions:
  * use the pam module: pam_pbssimpleauth.so. It is in the standard torque 
installation. It only gives access to a node if a user has a job running on 
the node.
  * in the contrib directory of torque there is a file: README.pam_authuser

We use the first one: pam_pbssimpleauth.so.
