User Databases

Dovecot obtains a user's [:UserIds:UNIX user ID (UID), UNIX group ID (GID)], home directory and [:MailLocation:mail location] from the user database after the user has been authenticated. The user database may also return [wiki:UserDatabase/ExtraFields extra fields] which are sent to the IMAP/POP3 process in environment variables.

The user and password databases may be the same or they may be different depending on your needs. You can also have [:Authentication/MultipleDatabases:multiple databases].

For more information about UID and GID, see UserIds.

For more information about home directory and mail location, see MailLocation.
