For this, why not just look at the objectCategory, and do a strcmp on
the first part of the DN. If it is msDS-isRODC then you have answered
your question. What is the need to actually consult the schema?
If you want the longer test for some reason, then the DN of the nTDSDSA
schema class is CN=NTDS-DSA,<schema DN>.

The operational code will currently allow you to ask for two attributes.
It should take a list, but I never got around to making it general. See
