User Databases ============== After a user has been successfully authenticated, Dovecot looks up the user's userdb information. The userdb lookup is also done by <LDA.txt> to find out how to deliver mails for the user. The user database lookup returns these fields: * *uid*: User's <UID> [UserIds.txt] (UNIX user ID) * *gid*: User's <GID> [UserIds.txt] (UNIX group ID) * *home*: <Home directory> [VirtualUsers.txt]. Although not required, it's highly recommended even for virtual users (see the link). * *mail*: <Mail location> [MailLocation.txt] (if needed to override the default 'mail_location' setting) * Optional <extra fields> [UserDatabase.ExtraFields.txt] which are passed to the IMAP/POP3 process in environment variables. The user and <password databases> [PasswordDatabase.txt] may be the same or they may be different depending on your needs. You can also have <multiple databases> [Authentication.MultipleDatabases.txt]. Currently supported user databases are: * <Passwd> [AuthDatabase.Passwd.txt]: System users (NSS, '/etc/passwd', or similiar) * <Passwd-file> [AuthDatabase.PasswdFile.txt]: '/etc/passwd'-like file in specified location * <NSS> [UserDatabase.NSS.txt]: Name Service Switch * <LDAP> [AuthDatabase.LDAP.txt]: Lightweight Directory Access Protocol * <SQL> [AuthDatabase.SQL.txt]: SQL database (PostgreSQL, MySQL, SQLite) * <Static> [UserDatabase.Static.txt]: Userdb information generated from a given template * <VPopMail> [AuthDatabase.VPopMail.txt]: External software used to handle virtual domains * <Prefetch> [UserDatabase.Prefetch.txt]: This assumes that the passdb already returned also all the required user database information (This file was created from the wiki on 2011-11-16 14:09)
