Grouper Developers Forum

Thanks again, Jim.  I installed it according to the README and it worked 
well.  However, it continued to connect and bind on each search, and 
never closed the context.  The ldap server quickly ran out of sockets. 
I started to debug it, but I couldn't find the 2.8.2 vt-ldap api docs. 
So, I downloaded 3.0 and converted it.  Works great now.  I also have it 
using a properties file, so much less is configured in sources.xml.  I 
have attached the patch between my new one and the only changed file 
(LdapSourceAdapter.java).

Sorry, you will see that I might have made a few unnecessary changes, 
also keep in mind that I am not really a Java programmer.
