Static User Database
====================

Static user database can be used when you want to use only single UID and GID
values for all users, and their home directories can be specified with a simple
template. The syntax is:

---%<-------------------------------------------------------------------------
userdb {
  driver = static
  args = uid=<uid> gid=<gid> home=<dir template>
}
---%<-------------------------------------------------------------------------

The home is optional. You can also return other <extra fields>
[UserDatabase.ExtraFields.txt]. You can use the standard <variables>
[Variables.txt] everywhere.

LDA and passdb lookup for user verification
-------------------------------------------

Unless your MTA already verifies that the user exists before calling
dovecot-lda, you'll most likely want dovecot-lda itself to verify the user's
existence. Since dovecot-lda looks up the user only from the userdb, it of
course doesn't work with static userdb because there is no list of users.
Normally static userdb handles this by doing a passdb lookup instead. This
works with most passdbs, with <PAM> [PasswordDatabase.PAM.txt] being the most
notable exception. If you want to avoid this user verification, you can add
'allow_all_users=yes' to the args in which case the passdb lookup is skipped.

Example
-------

---%<-------------------------------------------------------------------------
userdb {
  driver = static
  args = uid=500 gid=500 home=/home/%u
}
---%<-------------------------------------------------------------------------
