NAME
pam_rootok - Gain only root access SYNOPSIS
pam_rootok.so [debug] DESCRIPTION
pam_rootok is a PAM module that authenticates the user if their UID is 0. Applications that are created setuid-root generally retain the UID of the user but run with the authority of an enhanced effective-UID. It is the real UID that is checked. OPTIONS
debug Print debug information. MODULE TYPES PROVIDED
The auth, acct and password module types are provided. RETURN VALUES
PAM_SUCCESS The UID is 0. PAM_AUTH_ERR The UID is not0. EXAMPLES
In the case of the su(1) application the historical usage is to permit the superuser to adopt the identity of a lesser user without the use of a password. To obtain this behavior with PAM the following pair of lines are needed for the corresponding entry in the /etc/pam.d/su configuration file: # su authentication. Root is granted access by default. auth sufficient pam_rootok.so auth required pam_unix.so SEE ALSO
su(1), pam.conf(5), pam.d(5), pam(8) AUTHOR

Hello, Does anyone know the best way to create a user in Mac OS X with a specific UID? One (ugly) possibility seems to be to create the user, and then use netinfomanager to fix the UID, and then to run chown on all the user's files, but is there a more elegant way? Thanks, Noah (1 Reply)
