Hi All, I am trying to get Freeradius 1.1.7 on RHEL5 to authenticate using Active Directory. I have installed samba 3.0.28 and ran net join -U administrator, entered my password, and got this: Using short domain name -- UMPH Joined 'ITRADIUS' to realm 'UMPUBLISHING.ORG' When I do wbinfo -u I get users listed with the short domain name: UMPH\jdoe UMPH\mjohonson UMPH\ldaniel UMPH\.... . . etc If I put the following line in my /etc/raddb/users file, cyoho@umpublishing.org Auth-Type :- ntlm_auth AD authentication works for jdoe (or whatever user I put in users file) using radtest, NTradping, modem dialup, and just plain ntlm_auth on the command line. However, if I comment that line out, everything (radtest, dialup, NTradping, etc) fails with the following error in the debug output: rlm_realm: Looking up realm "umpublishing.org" for User-Name "jdoe@umpublishing.org" rlm_realm: No such realm "umpublishing.org" I enter the username as jdoe@umpublishing.org when attempting to login. I tried logging in using UMPH\jdoe, but that does not work either. I'd like to get it to work using the long realm, since our AD admin says that is our realm and our domain. Thanks in advance~ Cindy
