You don't understand or you don't want to understand?
Do you know, what "schema" means? It is a contract and validator for data
You pull up object, read its objectClass list, read its properties list, and
go over them comparing.
"Ahha, there we have an "uid" attribute. Where it is defined? Ahha, it was
posixAccount! Do we have objectClass=posixAccount? Aye, it's there. This
object is valid."
If object doesn't fit the contract, it is either violating or missing one.
Most likely violating. Do you seriously suggest me to create records that
violate the contract? And will likely get dropped by any migration software in
With best regards,
