keithstric.com :: lsxldap bug and Java Agent

OK, I posted earlier about a bug I've encountered with lsxldap. I never did find a way to get lsxldap to login and I've never gotten around to trying it on my home system. So, I broke down and wrote a Java agent to do my lookup. I gathered code from several sources and modified it and got it working. The biggest problem I encountered was trying to catch an InvalidAttributeValueException within a try/catch block. But instead of me rambling on with this as some of it I have no clue what it really does, here's the code I ended up with, hopefully someone will find a use for this...
