r22120: Expand the RPC-CRACKNAMES test, to test more values and expose patterns.
Fix up our server side implementation to pass almost all the tests (a couple are skipped). Don't require the DsGetDomainControllerInfo calls to pass, just get some info from them. Andrew Bartlett (This used to be commit a29eb8f7e541d2021726601faf52355e312c916b)
