pam_umask - PAM module to set the file mode creation mask
pam_umask.so [debug] [silent] [usergroups] [nousergroups] [umask=mask]
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:
The GECOS field is split on comma ',' characters. The module also in addition to the umask= entry recognizes pri= entry, which sets the nice priority value for the session, and ulimit= entry, which sets the maximum size of files the processes in the session can create.
Only the session type is provided.
Add the following line to /etc/pam.d/login to set the user specific umask at login:
session optional pam_umask.so umask=0022
