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= 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
