Gandalf asks for CHAP.

:S45: Couldn't find CHAP user ctrown-i

Is this user setup for chap?

: Look at the LCP_CONFIGURE_REQUEST with ID 32. The Gandalf is clearly
:asking for PAP authentication. Next, the PM3 sends a LCP_CONFIGURE_NAK to
:using CHAP. Huh? Where did that come from? Is that right?

Dunno, why but you have MPPP configged for this user? Is this the 2nd
channel coming up?

:side question, somewhat related, why did CHAP auth fail? I have a couple of
:other ISDN boxes that use CHAP successfully, via Radius.

Cus that user is not a chap user?
