The Rhosts authentication component
(pam_sm_authenticate
()), returns success if and only
if the target user's UID is not 0 and the remote host and user are listed in
/etc/hosts.equiv or in the target user's
~/.rhosts.
The following options may be passed to the authentication
module:
debug
- syslog(3) debugging
information at
LOG_DEBUG
level.
no_warn
- suppress warning messages to the user. These messages include reasons why
the user's authentication attempt was declined.
allow_root
- do not automatically fail if the target user's UID is 0.
