Is there a mechanism by which an ldap client can request for a specific schema element (attributetype, objectclass etc) using the OID or the textual name of the element.
No.
If not, 1. Should this be done by the matched values extension. http://sec.isi.salford.ac.uk/download/MatchedValues-06.txt. The draft has expired quite sometime bac.
This would be the right solution.
2. Can we consider special casing the schema search for assertions like attributetypes=<attrname or oid> to only return the matched value ? The 2nd option seems preferable.
