[jira] Commented: (DIRSERVER-1301) Colliding attributeType and objectClass names not supported, error messages unhelpful

    [ https://issues.apache.org/jira/browse/DIRSERVER-1301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12744443#action_12744443 ] 

Emmanuel Lecharny commented on DIRSERVER-1301:
----------------------------------------------

We must review the OidRegistry in order to allow such name collisions. Basically, we always know which kind of SchemaObject we are dealing with, we then should pass it to the OidRegistry when registering or searching for some name.

> It seems like when resolving the may list of objectClass "port", the OID was resolved to the OID of attribute "ship", not objectclass "ship".
> Two things to note here:
> 1) Netscape/Red Hat/Fedora Directory server supports adding objectClasses that have a name that's colliding with an attributeType's name.
> 2) Even if such behaviour violates an RFC (I'm not aware of such limitations), the exception should point out that name collisions between objectclasses and attributenames aren't allowed.
> I think that the OID registries should be separate for attributeTypes and objectClasses.
