Add a verification before deleting an Object Class in the schema
----------------------------------------------------------------

                 Key: DIRSERVER-888
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-888
             Project: Directory ApacheDS
          Issue Type: Improvement
    Affects Versions: 1.5.0
            Reporter: Pierre-Arnaud Marcelot


While I was playing a little with the new dynamic schema in ADS 1.5, I found an interesting
situation.

Here's the scenario:
I created a new AT called 'MyAT' and a new OC called 'MyOC' which has 'MyAT' in its May list.

After a refresh of the Connection in LDAP Studio, I was able to create a new entry using 'MyOC'
as OC. This entry was 'MyAT=test, dc=example, dc=com'.

Then I was wondering how would react the server if I delete 'MyAT' from the schema.
I got a warning telling me that an entity was depending on it (it was 'MyOC' of course).
Very Great! :)

Then I tried to delete 'MyOC'... and then... no warning...
I could delete it successfully.

After that, I was also able to delete 'MyAT', since there was no more dependency on it.

That left my server with a pretty strange situation : having an entry depending on OC and
AT that doesn't exists anymore in the schema...

While trying to load children of 'dc=example, dc=com', I got an error : "Error while reading
entry
  [LDAP: error code 33 - failed on search operation: OID for name 'myoc' was not found within
the OID registry]"

I think it would be a good idea, before deleting an OC in the schema, to verify if there's
not one (or more) entry depending on that OC.
