This module performs the standard network authentication for services, as used by traditional implementations of rlogin and rsh etc.
The authentication mechanism of this module is based on the contents
of two files;
~/.rhosts. Firstly, hosts listed in the
former file are treated as equivalent to the localhost. Secondly,
entries in the user's own copy of the latter file is used to map
"remote-host remote-user" pairs to that user's
account on the current host. Access is granted to the user if their
host is present in
/etc/hosts.equiv and their
remote account is identical to their local one, or if their remote
account has an entry in their personal configuration file.
The module authenticates a remote user (internally specified by the
PAM_RUSER connecting from the remote
host (internally specified by the item PAM_RHOST).
Accordingly, for applications to be compatible this authentication
module they must set these items prior to calling
pam_authenticate(). The module is not capable
of independently probing the network connection for such information.
