NAME
pam_umask - PAM module to set the file mode creation maskSYNOPSIS
pam_umask.so
[debug] [silent] [usergroups] [nousergroups] [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= entry in the user's GECOS
field
•umask= argument
•UMASK entry from /etc/login.defs
•UMASK= entry from
/etc/default/login
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.
OPTIONS
debugPrint 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).
nousergroups
This is the direct opposite of the usergroups
option described above, which can be useful in case pam_umask has been
compiled with usergroups enabled by default and you want to disable it at
runtime.
umask=mask
Sets the calling process's file mode creation
mask (umask) to mask & 0777. The value is interpreted as
Octal.
