By +default it permits access to the target user if the applicant user is a member +of the wheel group. If no group with this name exist, the module is using the +group with the group-ID 0. + +OPTIONS + +debug + + Print debug information. + +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 (or the group of the group + option), deny access. Conversely, if the user is not in the group, return + PAM_IGNORE (unless trust was also specified, in which case we return + PAM_SUCCESS). + +group=name + + Instead of checking the wheel or GID 0 groups, use the name group to + perform the authentication. + +root_only + + The check for wheel membership is done only when the target user UID is 0. + +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). + +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). + +EXAMPLES + +The root account gains access by default (rootok), only wheel members can +become root (wheel) but Unix authenticate non-root applicants. + +su auth sufficient pam_rootok.so +su auth required pam_wheel.so +su auth required pam_unix.so + + +AUTHOR + +pam_wheel was written by Cristian Gafton <gafton@redhat.com>. + |
