Hi there,

I had the issue when I tried to configure my freeradius server integrate windows 2008 R2 Active directory authentication.  It worked before when it connected to a Windows AD 2003. However after I switched the AD server to a new AD server which is in another Windows domain (windows 2008 R2) , it’s broken.  Looks like the radius server doesn’t forward the request to the AD server even it has no Mysql  database or local user database. The request was rejected then. All the AD integration configuration files are in place and I don’t find any mistakes.  The only change I made is  upgrading the samba version from 2.x to 3.5.4 because the old version can’t build up pipe to windows 2008 R2 domain controller.

1. The radius server has already joined the windows 2008 R2 domain.  I can look up the AD information without problem.

a. Samba version:

[root@GTK_RADIUS /]#smbd -V

Version 3.5.4-0.83.el5

b. authenticate a user from the domain

[root@GTK_RADIUS /]#wbinfo -a exie%123456

plaintext password authentication failed

Could not authenticate user exie%123456 with plaintext password

challenge/response password authentication succeeded

c. authenticate with NTLM

                                 [root@GTK_RADIUS /]#ntlm_auth .-request-nt-key --domain=NE --username=exie

                                  password:

                                  NT_STATUS_OK: Success (0x0)

2. The Log of Radius authentication is attached.

Could you kindly to help me figure out why the freeradius server can’t work with windows AD? Thanks so much in advance.
