.Sh DESCRIPTION
|
|
The NoLogin service module for PAM,
|
|
.Nm
|
|
provides functionality for only one PAM category:
|
|
account management.
|
|
In terms of the
|
|
.Ar module-type
|
|
parameter, this is the
|
|
.Dq Li account
|
|
feature.
|
|
.Ss NoLogin Account Management Module
|
|
The NoLogin account management component,
|
|
.Fn pam_sm_acct_mgmt ,
|
|
verifies whether logins are administratively disabled via
|
|
.Xr nologin 5 .
|
|
It returns success if the user's login class has an "ignorenologin"
|
|
capability specified in
|
|
.Xr login.conf 5
|
|
or the
|
|
.Xr nologin 5
|
|
file does not exist.
|
|
If neither condition is met,
|
|
then the contents of
|
|
.Xr nologin 5
|
|
are echoed
|
|
before failure is returned.
|
|
The location of
|
|
.Xr nologin 5
|
|
is specified by a "nologin" capability in
|
|
.Xr login.conf 5 ,
|
|
which defaults to
|
|
.Pa /var/run/nologin .
|
|
.Pp
|
|
The following options may be passed to the module:
|
|
.Bl -tag -width ".Cm no_warn"
|
|

|
|
.Xr syslog 3
|
|
debugging information at
|
|
.Dv LOG_DEBUG
|
|
level.
|
|
.It Cm no_warn
|
|
suppress warning messages to the user.
|
|
These messages include
|
|
reasons why the user's
|
|
login attempt was declined.
