Understand AD Bridge Cells and their Roles
An AD Bridge cell is a container of Unix settings for Active Directory users and groups so they can log into Linux and Unix computers.
For each user, the settings include a Unix user identifier (UID), the group identifier (GID) of the primary group, a home directory, and a login shell.
You can use cells to map a user to different UIDs and GIDs for different computers.
