PPTP EAP TLS (I recognize this might be outdated)
Last Post: March 5, 2011:
Just out of curiosity, could PPTP be used with TLS. My first understanding is that TLS is for a short term connection for authentication, so how could it used? I only asked because I saw a very old posting on the internet that indicated that Microsoft advises to use EAP-TLS with PPTP, which didn't really make sense to me, but technically it isn't going to give a encryption, could I get some input on this one. Thanks.
I have to admit that I do not have any first hand experience in this, but from research, PPTP is not an authenticating protocol (meaning its not written to communicate between AS server and client). It is a legacy L3 encryption protocol, which means data. In addition, TLS is strongly advised to be used for legacy authenticating protocols ie.PAP AND CHAP. Maybe that's what you saw?
