pam_umask.so [debug] [silent] [usergroups] [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:
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
Print debug information.
Don't print informative messages.
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).
Sets the calling process's file mode creation mask (umask) to mask
& 0777. The value is interpreted as Octal.
