Quanah Gibson-Mount commented on DIRSTUDIO-513:
-----------------------------------------------

Stefan,

I think the problem is more that some people choose to hide their schema from being read out of the subschema entry, which is a perfectly valid thing to do.  So any well written LDAP client needs to be able to work with the fact that the schema may or may not be browsable.  There is even some security suite out there that "warns" people that exposing the subschema entry is a security risk.  Not that I agree with it. ;)

> When connecting to Novell eDirectory and modifying the schema an "Attribute Or Value Exists" error occurs.  This is due to the modification performing an add before the delete and eDirectory (wrongly) complains that the same OID has been used more than once before realising that the old value should be deleted.  Note that this is a problem with eDirectory but it would be useful if Studio asked for the delete to be performed before the add when modifying an attribute value which eDirectory is OK with.
> An example of the LDIF in the modifications logs view for an operation that fails is:
> dn: cn=schema
> changetype: modify
> add: objectClasses
> objectClasses: ( 2.16.840.1.113730.3.2.2 NAME 'inetOrgPerson' [...new value...]
> -
> delete: objectClasses
> objectClasses: ( 2.16.840.1.113730.3.2.2 NAME 'inetOrgPerson' [...old value...]
> -
> It also seems that modifying the schema on ApacheDS has the same issue.
