Hi everyone, I've installed a FreeRadius server for authentification over a Active Directory with a ntlm authentification. But since few day it doesn't work anymore. When i try ntlm_auth in command line, i get that : /[root@centosrad samba]# ntlm_auth --username=testrad --domain=CITRIX --diagnostics password: Access denied (0xc0000022) [2012/06/11 11:56:19, 1] utils/ntlm_auth_diagnostics.c:diagnose_ntlm_auth(599) Test LM failed!
