Yep, There is another one out there that I started and Chandru  
finished off. Fixed schema (several fixed schemas actually). It is  
nothing more than a pattern match across the asn.1 structures (which  
could be directly taken from from eldap), with a simple state machine  
to cover bind (login).

It was very fast.
