Mate, I wasn't arguing in the sense of "you're wrong", I was just trying 
to understand why were you saying that LDAP wasn't working, when it 
clearly looked like it was. After you explained the difference between 
PAP and MS-CHAP on the previous email, I could finally understand just 
that. So thanks once again for the explanation!

And yeah, I didn't know what was going on, but that was my reason to 
come here in the first place!
