Hi Charles, I already have defined NTLM Security policy for my Domain Controller security settings. But Still getting the same error message. Can you please specify the local domain controller policies with settings which should be enabled for Freeradius server to authenticate.

error code was NT_STATUS_CANT_ACCESS_DOMAIN_INFO (0xc00000da)

error messsage was: NT_STATUS_CANT_ACCESS_DOMAIN_INFO

This error indicates that something went wrong with the domain access. Try to troubleshoot by using wbinfo -g or wbinfo -u. With these commands you should be able to list the users and groups of your domain. There may be a problem with NTLM on your Windows2003 server. Note thath NTLM was the authentication protocol used by earlier version of Windows. It is still supported for backward compatibility, but can be disabled. By default, Win2k and 2003 use Kerberos for authentication. You might have a security policy thats restricts the use of NTLM on your network. Check your GPO if NTLM is allowed to be transmitted across the network. Regards, Charles Schwartz

Hi,

I used the document freeRadius_AD_tutorial.pdf for configuring a linux

box to get authenticated through users in Windows 2003 AD.

I used the command net join -U Administrator to add the machine to the

domain. It gave successful results. Now on typing the command

wbinfo -a checkad%Quark_123

I got the following results:-

plaintext password authentication failed

error code was NT_STATUS_NO_SUCH_USER (0xc0000064)

error messsage was: No such user

Could not authenticate user checkad%Quark_123 with plaintext password

challenge/response password authentication failed

error code was NT_STATUS_CANT_ACCESS_DOMAIN_INFO (0xc00000da)

error messsage was: NT_STATUS_CANT_ACCESS_DOMAIN_INFO

Could not authenticate user checkad with challenge/response

Also, on giving the command

# ntlm_auth --request-nt-key --domain=india.quark.com --username=

checkad

password:

NT_STATUS_CANT_ACCESS_DOMAIN_INFO: NT_STATUS_CANT_ACCESS_DOMAIN_INFO

(0xc00000da)

[root@Radius etc]#

I get the above stated error. Please help.

Thanks & Regards
