[Samba] ntlm_auth from pppd help

[Brian Hoover]

Hello all,

I am working on a VPN solution using FC3-2.6.12-1.1381 - openswan
2.4.4-1 - l2tpd 0.69-13 - pppd 2.4.3-5 - samba 3.0.10-1.

When attempting a connection from an XP-SP2 box pppd dies without
authenticating the user (see below).
I have run ntlm_auth from the command line with success.

What tools can I use to identify the failure?

Is there an obvious error in the ppp options file? 

Thanks,
Brian Hoover
