Hi Shawn,

Thanks again for the response.

I'll do some more log analysis and see if I can confirm the root cause.

On the indexing: I did already find the page you indicated and I did attempt to 
add an index on the cn of our user records.  I'm a bit clueless as to whether 
this is the correct field to index and on the correct process/steps to add the 
index (that page is a bit scant on details).  I added the index via directory 
studio, saved the config and restarted the ApacheDS service - does that sound 
like the correct process or are there other steps?

Regards,

Matthew

Also, when you observe the behavior of slow binds, what kind of load is the 
machine under?

Some basic info here:
https://directory.apache.org/apacheds/configuration/ads-2.0-configuration.html

Also, on logging, as I encourage you to pinpoint the problem using the logs.  
It very well could give you insight as to what's going wrong.

Good luck.
