What You've Learned

• Directory services allow multiple processes to access common system data, such as user information.

• Data can be stored on a network server, allowing multiple computers to access the same data.

• With proper configuration, the same user account can be used to log into multiple computers on the network, rather than tying the user to a single computer.

• User records are the most frequently used record type and store information to uniquely identify a user.

• Group records define one or more users that should share certain system permissions.

• If a replica is separated from all other replicas by a slow network link and that replica fails, clients of the replica will fail over to a replica on the other side of the slow network link.

• You can increase the size of the BerkeleyDB cache to improve performance of the database.

• The Kerberos KDC uses TCP/UDP port 88; TCP/UDP port 749 is used for Kerberos administration.
