|
.Sh DESCRIPTION
|
|
The group service module for PAM accepts or rejects users based on
|
|
their membership in a particular file group.
|
|
.Nm pam_group
|
|
provides functionality for two PAM categories: authentication and
|
|
account management.
|
|
In terms of the module-type parameter, they are the ``auth'' and
|
|
``account'' features.
|
|
.Pp
|
|
The following options may be passed to the
|
|
.Nm
|
|
module:
|
|
.Bl -tag -width ".Cm fail_safe"
|
|
.It Cm deny
|
|
Reverse the meaning of the test, i.e., reject the applicant if and only
|
|
if he or she is a member of the specified group.
|
|
This can be useful to exclude certain groups of users from certain
|
|
services.
|
|
.It Cm fail_safe
|
|
If the specified group does not exist, or has no members, act as if
|
|
it does exist and the applicant is a member.
|
|
.It Cm group Ns = Ns Ar groupname
|
|
Specify the name of the group to check.
|
|
The default is
|
|
.Dq Li wheel .
|
|
.It Cm luser
|
|
Accept or reject based on the target user's group membership.
|
|
.It Cm root_only
|
|
Skip this module entirely if the target account is not the superuser
|
|
account.
|
|
.It Cm ruser
|
|
Accept or reject based on the supplicant's group membership.
|
|
This is the default.
|
|
.El
|
|
.Pp
|
|
Note that the
|
|
.Cm luser
|
|
and
|
|
.Cm ruser
|
|
options are mutually exclusive, and that
|
|
.Nm
|
|
will fail if both are specified.
