I suggest you attempt an anonymous bind.  This should always return
a result (possibly indicating an error).  If you want to force an
error, select version MAXINT.

Or ask for attribute "1.1"... (you'll have less to throw away).

Anonymous bind.  In fact, I suggest as a cheap general solution
for all versions of LDAP.  Anonymous binds are generally quite
cheap... in fact may be even cheaper than accessing the LDAPv3
root DSE (depending on implementation).
