PAM/NSS-DCE for Linux is a nice and portable way to integrate Linux clients into existing DCE/DFS environments. The basic idea is to make use of PAM (Pluggable Authentication Modules) and NSS (Name Service Switch). DFS access is gained using the so-called NFS to DFS gateway that comes with DCE/DFS. A PAM module is used to authenticate against the DCE registry and to set up the appropriate NFS/DFS mappings. A separate NSS module is responsible for the name service lookups.
