Why don't you just do a lookup for the rootDSE then ? It's most 
certainly the fastest operation, and you don't need to be bound. If you 
want to check that a user can bind, then just do a bind.

Usually, you never start searching a directory starting from the 
rootDSE, this is not the way to proceed. LDAP defines NamingContexts for 
this purpose.
