ACK

My biggest problem with OpenLDAP, or any LDAP, is (other than my 
ignorance) the fact that all of them (save for AD) started with an empty 
schema.  So I was functionally needing to create a schema that was 
hopefully compatible with the things I needed /while/ learning LDAP ~> 
$LDAPimplementation.  I always felt it was a relatively steep learning 
curve.  And I was never sufficiently motivated.

Conversely, AD, has a very well established LDAP schema and many things 
know how to work with it.

Do you by chance know any more details?  I'll dig and see if I can find it.

I think I understand that.  Or at least what (little) I know doesn't 
doesn't seem to have any objection to that.  I know that I would not 
want to use LDAP as a general purpose relational database.

Thank you for the ProTip.
