Access Control List (ACL)

Collection of all ACE's that define the permissions of a share, file, directory, etc.

Active Directory (AD)

Directory service developed by Microsoft. Samba version 3 could only be member of an AD as file server, Samba since version 4 can also be Domain Controller of an AD. For a detailed description, see https://en.wikipedia.org/wiki/Active_Directory.

Active Directory Users and Computers (ADUC)

It is an MMC snap-in for managing e. g. user and computer accounts.



B

Backup Domain Controller (BDC)

In an NT4 domain, the BDC is a computer having a copy of the user and groups database. Changes are always done on the PDC. The Backup Domain Controller is only read-only. Changes are pushed from the PDC via Master-Slave-Replication to the BDC(s). In case of an outage of an PDC, a BDC can be promoted to an PDC.
