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:

       ·   umask= argument

       ·   umask= entry of the users GECOS field

       ·   pri= entry of the users GECOS field

       ·   ulimit= entry of the users GECOS field

       ·   UMASK= entry from /etc/default/login

       ·   UMASK entry from /etc/login.defs

OPTIONS

       debug
           Print debug information.

       silent
           Don't print informative messages.

       usergroups
           If the user is not root 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.

MODULE TYPES PROVIDED

       Only the session type is provided.

RETURN VALUES

       PAM_SUCCESS
           The new umask was set successfully.
