Good point on TLS. The /etc/ldap.secret is where I had the problem. If 
you put that file on an end users machine, wouldn't they be able to boot 
into single user mode or sudo and read that file? Doesn't that file 
provide the keys to the kingdom? Once you have full read access to the 
directory. can't you read all the user id's and hashes and gain access 
to every other system? Sorry if this was already a hackfest activity and 
I missed it.
