[Samba] ntlm_auth from pppd help

[Juha Pietikäinen]

I have the same problem. My setup is same except my server is FC1 with
kernel 2.4.32 and samba 3.0.21rc1.

See "Unified logons with winbind and tdbsam backend":
http://lists.samba.org/archive/samba/2005-November/113583.html
I didn't get any responses to my message which I sent couple times here.

I can't say for sure is this a samba bug or a configuration issue.

Ppp-debug option gives following error messages:
utils/ntlm_auth.c:manage_squid_request(1592)
fgets() failed! dying..... errno=1 (Operation not permitted)
Peer DOMAIN\\user failed CHAP authentication
