[Exim] Is there any classic schema for Exim-LDAP (OpenLDAP-2…

Hello,

Is there any classic schema for Exim-LDAP (OpenLDAP-2)? I didn't find
any schema files in Exim distribution.

I have made a test about Exim-MySQL performance. If mailboxes in MySQL
are more than 200000, it takes a lot of time in mysql lookups. So I want
to know how Exim-LDAP works, faster or slower?

Is there any comparison between Exim-MySQL and Exim-LDAP? It's so hard
to make a decision.

Thanks a lot.
