pam_group(8)              BSD System Manager's Manual             pam_group(8)

NAME
     pam_group -- Group PAM module

SYNOPSIS
     [service-name] function-class control-flag pam_group [options]

DESCRIPTION
     The Group PAM module supports the account management function class.  In terms of the function-class
     parameter, this is the ``account'' class.

     The Group account management module permits or denies users based on their membership to a particular
     group (or groups) specified with the group option.  If no groups are specified the default group
     (``wheel'') will be used.

     The following options may be passed to this account management module:

     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.

     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.

     group=groupname
                 Specify the name of the group to check.  This can be a comma-separated list (i.e.
                 ``group=admin,wheel'').

     root_only   Skip this module entirely if the target account is not the superuser account.

     ruser       Check the membership of the applicant (PAM_RUSER), rather than the target account
                 (PAM_USER)
