Add shim to autocreate directory by default when homes directory functionality is enabled in CIFS
We had a user run into an issue where they integrated [[FreeNAS]] in AD and the problem was that the home directories for arbitrary users weren't automatically created when users logged into the box.
There are two issues that need to be resolved/enhanced:
1. If the user logs in, the directory should be automatically created for the user.
2. The directory should be populated with files from /usr/share/skel , s.t. the user will can login via the shell if need be and the administrator permits it (i.e. account logins are not disabled and the shell isn't set to /sbin/nologin).
