PAM_UMASK(8)		       Linux-PAM Manual			  PAM_UMASK(8)

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

       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.
