DESCRIPTION
The NoLogin authentication service module for PAM provides functionality for
only one PAM category: authentication. In terms of the
module-type parameter, this is the
“
auth
” feature. It also provides a null
function for session management.
NoLogin Authentication
Module
The NoLogin authentication component (
pam_sm_authenticate()),
always returns success for the superuser, and returns success for all other
users if the file
/etc/nologin does not exist. If
/etc/nologin does exist, then its contents are echoed to
non-superusers before failure is returned. If a "nologin" capability
is specified in
login.conf(5), then the file
thus specified is used instead. This usually defaults to
/etc/nologin.
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.
