pam_umask


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 (influenced by USERGROUPS_ENAB in
           /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). Note that using this
           option explicitly is discouraged. pam_umask enables this
           functionality by default if /etc/login.defs enables
           USERGROUPS_ENAB, and the umask is not set explicitly in other
           places than /etc/login.defs (this is compatible with login's
           behaviour without PAM).

       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.
