NAME
       pam_umask - PAM module to set the file mode creation mask

SYNOPSIS
       pam_umask.so [debug] [silent] [usergroups] [umask=mask]

DESCRIPTION
       pam_umask is a PAM module to set the file mode creation mask of the current environment.
       The umask affects the default permissions assigned to newly created files.

       The PAM module tries to get the umask value from the following places in the following
       order:

       o   umask= argument

       o   umask= entry of the users GECOS field

       o   pri= entry of the users GECOS field

       o   ulimit= entry of the users GECOS field

       o   UMASK= entry from /etc/default/login

       o   UMASK entry from /etc/login.defs

       debug
           Print debug information.

       silent
           Don't print informative messages.

       usergroups
           If the user is not root, and the user ID is equal to the group ID, and the username is
           the same as primary group name, the umask group bits are set to be the same as owner
           bits (examples: 022 -> 002, 077 -> 007).

       umask=mask
           Sets the calling process's file mode creation mask (umask) to mask & 0777. The value
           is interpreted as Octal.
