Root DSE and subschema queries/compares

[Jim Sermersheim <JIMSE@novell.com>]

People would like to perform compare operations on attributes of the root DSE and/or subschema subentry, but I don't see any obvious provisions for doing this.

In order to read the root DSE and subschema subentry, you must specify a particular filter: "(objectclass=*)" for root DSE and "(objectclass=subschema)" for the subschema subentry. I can't find anything that talks about whether the compare operation is allowed (this should also be mentioned in the subentry draft).

If it were allowable to perform a compare operation on these entries, the requirement above would be met. Alternately, we could allow the search filter to contain more information such as: "&(objectclass=*)(supportedControl=1.2.3.4)" on a root DSE query would only return the root DSE if it had 1.2.3.4 in the supportedControl attribute. Same notion for schema entries.

Any feelings on how to do this?
