Re: Ldap

Actually, I'm doing it...
I use shell backend to translate OpenLDAP query to SQL query and passing the
result back to OpenLDAP.
All ldap operations (add/del/modify/modrdn .. etc) are supported. The whole
things are transparent to client.

Too bad I can't make it 'open source' (techinally I can, but expect to get
fired on the following day..).
Performance is of course a little slower compared to native backend. But,
short development time alone far
outweight the tiny performance hit.

If you don't expect your ldap server to get huge access everyday, then you
might want to look into this approach.
