RRAS Server on a Domain to use local authentication

Hello everyone,

I have a Windows 2003 Server running RAS.  I have been trying to establish a dial-in connection to this server from another pc using CHAP authentication.  I have been able to make a connection when the server is not part of our domain.  However, I need this server to be a member of the domain.  When it is on the domain, I get an error saying that the user failed to authenticate.

I know that reversibly encrypted passwords need to be enabled, and I have done that.  I have reset the passwords so that this setting will catch.  I have set up each user to allow dial-in connections.  Encrypted passwords and dial-in settings are the same on both the local server and our PDC.

As a workaound, is there a way i can have the RAS server join the domain, but authenticate dial-up users locally???  Also, if anyone has any ideas as to how I can make this work by using the PDC to authenticate these users, that would help too.  Thanks!

Ok, I think I found where the problem occurs.  In the IASSAM.LOG file, there are errors stating:

Opening LDAP connection to server.domain.local.
Access denied -- purging Kerberos ticket cache.
Retring LDAP connection to server.domain.local.
LDAP connect failed: Access is denied.
Using downlevel dial-in parameters.
Could not open an LDAP connection to domain DOMIAN.
NTDomain::getConnection failed: Access is denied.
Per-user attribute retrieval failed: Access is denied.

So I imagine that some type of setting in the active directory is causing this.  I have no idea how to fix this.  Any ideas???

I added the RAS server to the list of RAS and IAS servers in the Active Directory group on our PDC.  I also rejoined the domain, then logged into the RAS server using a domain login.  It now works.  I'm not exactly sure why, but i'm glad it does.  Problem solved.
