Yes.

suffix "ou=users,dc=domain,dc=net" rootdn "cn=Manager,dc=domain,dc=net" [..] suffix "ou=profiles,dc=domain,dc=net" rootdn "cn=Manager,dc=domain,dc=net"

Note that the rootdn in each database has to be within this particular naming context like this:

database mdb suffix "ou=users,dc=domain,dc=net" rootdn "cn=Manager,ou=users,dc=domain,dc=net" [..] database mdb suffix "ou=profiles,dc=domain,dc=net" rootdn "cn=Manager,ou=profiles,dc=domain,dc=net"

The rootdn has only manage privilegs (no ACLs are in effect) in its own DB.

Ciao, Michael.

Yes, it is possible.

You have several choices: 1. create a primary database with suffix dc=domain,dc=net and attach the other databases as subordinate databases. 2. attach this 2 databases to a meta backend. 3. you may have a look at man slapd-relay(5).

But none of these have any influence on index efficiency.
