pam_umask - PAM module to set the file mode creation mask
SYNOPSIS
pam_umask.so [debug] [silent] [usergroups] [umask=mask]

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
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.
PAM_SERVICE_ERR
No username was given.
PAM_USER_UNKNOWN
User not known.
EXAMPLES
Add the following line to /etc/pam.d/login to set the user specific umask at login:
session optional pam_umask.so umask=0022
