A modular and thread-enabled tool to create and/or mounting and managing automagically and transparently user/group home directories, on demand.

It can work with any authentication framework (e.g. system files, NIS, LDAP or SQL) and does not require PAM, which is a required feature for session-less service such as smtp servers.

Automounter version 4 (autofs4) has to be enabled when compiling the kernel. Debian packaged kernels have it enabled as module.
