Re: LDAP Schema

Given the semantics of the ldap_modify operation, deleting an objectclass
and adding the modified defintion seems like a possible way out of the
problem. One can make it atomic by chaining the modify request such that the
delete & add happens in one single operation and either the entire operation
succeeds or the all the changes in the operation are discarded.
This, of course, pushes the burden on the users/administrators to use the
right modify request.
