9 pam_groupmember

The pam_groupmember module checks whether the user is member of one or more groups. Both primary and supplementary groups are checked. The list of groups to be checked is given with the groups option. Its argument is a comma-separated list of group names of numeric IDs, prefixed with ‘+’ sign.

The module returns PAM_SUCCESS if the user is member of one of the supplied groups and PAM_AUTH_ERR on otherwise. The return value can be inverted using the sense=deny option.

Additionally, the module can return PAM_USER_UNKNOWN if the user is not known and PAM_AUTHINFO_UNAVAIL if unable to retrieve the user name.

The pam_groupmember module can be used in any PAM service stack.
