MSCHAP failing on new 2.1.10 install

[Gary Gatten]

PS: I apparently have to leave the "DEFAULT Auth-Type = ntlm_auth "  in the users file or "nothing" works.  FWIW I am exclusively using AD/ntlm_auth for all auth types, so hopefully this won't matter?  I did find a Wiki article about updating the control such that if Auth-Type doesn't exist then set it to ntlm_auth.  I have this in my 2.1.6 deployment, so may copy it over here as well.  I'm trying to change as little as possible from the default confs....

Subject: MSCHAP failing on new 2.1.10 install

PAP works, MSCHAP fails - specifically MSCHAPv2.

This is a fresh install of 2.1.10, built from source.  I'm using ntlm_auth; samba version 3.0.33-3.7.el5  I also have version 2.1.6 running on the same box and it "mostly" works: seems to work with everything except Winblows7, hence I installed 2.1.10 in a different dir structure and it's listening on different ports.  I just tested a login using the same user account and pw; works great on 2.1.6 but fails on 2.1.10.  I've tried 4 or 5 different command strings for ntlm_auth - no go.  It's as if mschap is not using ntlm_auth, but not sure.  I'll keep checking and googling, but any hints would be appreciated!  TIA!  Gary


I've changed only the minimum from the default, clients.conf and the recommended for integrating with AD:
