Many thanks for your quick responses!!

When I originally developed this, 1.5.6 was the most recent version.  I 
tried creating an LDAPPartition on this version but had a number of 
problems (all the samples showed how to implement this for 1.5.5 and 
there were some large API changes under the covers).  So I stuck with 1.5.5.

The following article also seems to still talk about 1.5.5.  -

Are their samples of how to implement a custom partition in 1.5.7?    
I'd love to be able to do a quick verification that the root search is 
fixed before doing a full port.

Thanks again,
