Then you should probably dig into ietf-ldapbis mailing list archives. I
suspect that question you will ask were already asked by myself, most times on

It's the so-called "minimum upper bound". It's rather useless for UI.

I'm looking forward to your implementation. You should test it with many servers.

But you should really consider whether you want to waste so much spare time on

little better today because server implementations are much more LDAPv3
compliant than they used to be.
