NAME
pam_group —
Group PAM module
SYNOPSIS
[service-name] module-type control-flag pam_group [arguments]
DESCRIPTION
The group service module for PAM accepts or rejects users based on their membership in a particular file group.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.
The following options may be passed to the
pam_group 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. The default is
“
wheel”. luser- Accept or reject based on the target user's group membership.
root_only- Skip this module entirely if the target account is not the superuser account.
ruser- Accept or reject based on the supplicant's group membership. This is the default.
Note that the luser and
ruser options are mutually exclusive, and that
pam_group will fail if both are specified.
