That makes the SQL backend like Luke mentioned the remaining alternative
as far as current OpenLDAP is concerned.  I don't know back-sql myself.

Howard Chu tells me he's also playing with a new backend using MySQL's
NDB which is their cluster-engine backend for mysqld.  Not itself an SQL
backend - there's no SQL involved in the actual LDAP operations.

A bit confusion here.  The LDBM backend was removed from OpenLDAP 2.4.
It supported several database libraries including Berkeley DB 1.x.
The sturdier BDB backend is now default, and requires Berkeley DB 4.x.

No.  The BDB backend needs many features missing from DB 1.
And it needs them to work right, which means DB 4.2, 4.4 or later.


I missed this one:

Yes.  One way or another it'll need an LDAP server.  Howard
mentioned an NSS overlay to slapd - that means a module ("nssov")
which can be plugged into the slapd server, if that wasn't clear.
