-pam_wheel:
- only permit root authentication too members of wheel group
-
-RECOGNIZED ARGUMENTS:
- debug write a message to syslog indicating success or
- failure.
-
- use_uid the check for wheel membership will be done against
- the current uid instead of the original one
- (useful when jumping with su from one account to
- another for example)
-
- trust the pam_wheel module will return PAM_SUCCESS instead
- of PAM_IGNORE if the user is a member of the wheel
- group (thus with a little play stacking the modules
- the wheel members may be able to su to root without
- being prompted for a passwd).
-
- deny Reverse the sense of the auth operation: if the user
- is trying to get UID 0 access and is a member of the
- wheel group, deny access (well, kind of nonsense, but
- for use in conjunction with 'group' argument... :-)
-
- group=xxxx Instead of checking the GID 0 group, use the xxxx
- group to perform the authentification.
-
-MODULE SERVICES PROVIDED:
- auth _authetication and _setcred (blank)

-/*
- * Written by Cristian Gafton <gafton@redhat.com> 1996/09/10
- * See the end of the file for Copyright Information
- *
- *
- * 1.2 - added 'deny' and 'group=' options
- * 1.1 - added 'trust' option
- * 1.0 - the code is working for at least another person, so... :-)
- * 0.1 - use vsyslog instead of vfprintf/syslog in _pam_log
- * - return PAM_IGNORE on success (take care of sloppy sysadmins..)
- * - use pam_get_user instead of pam_get_item(...,PAM_USER,...)
- * - a new arg use_uid to auth the current uid instead of the
- * initial (logged in) one.
- * 0.0 - first release
- *
- * TODO:
- * - try to use make_remark from pam_unix/support.c
- * - consider returning on failure PAM_FAIL_NOW if the user is not
- * a wheel member.
