Hi, I was setting up NTLM auth against AD and it works well however I wanted to add another server sections in the config and that was working ok too up to the point when somebody wants to do mschap authentication against something else than AD I followed the recommendations and add the following: with_ntdomain_hack = yes ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username={mschap:User-Name:-None} --domain={mschap:NT-Domain:-WEBANGEL} --challenge={mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00}"
to the module section in mschap but now it seams that it cannot do any other backends I have sql engine returning ok before mschap and than mschap returning reject and whole request is rejected. I attach log of activity from radius -X I would like to have two separate server sections one authenticating against AD and the other against SQL and I would like the end-client to be able to use MSCHAPv2 to use both. Thank you in advance for your help. Regards Paul
