Remote AD SSO keeps failing

I'm having AD SSO issues where our new Sophos 120 units at our branch offices in NY and FLA keep disconnecting from our primary AD server in AZ and because of that, our users there are getting pop-ups for authentication. To resolve this issue I had to re-join the domain and it'll work for 3 to 4 hours and then it breaks again.

We have Win2008 R2 RODC servers at both locations under one domain name.

The Sophos units are all connected via Site to Site VPN (IPSEC - AES256). MTU Discovery is checked at all remote gateways.

We have an older Astaro 320 here at the main office in AZ. All units are on 8.306 (Can't wait for v9 to come out)

The web filter log shows this when users can not authenticate: (this log also appears on the FLA unit as well)

AD SSO works well at the AZ site and I'm guessing there might be some tweaking that needs to be done on the VPN side?

Thanks for re-editing the logs as they are easier to read...

You're welcome - you can edit your own post so you can see the [/CODE] at the end after the

 at the beginning.



Well, I'm a bit confused as the FQDN in your URL resolves to an OpenDNS IP in California - does that mean you have a common WPAD file there for all of your offices?  In the WPAD file, the proxy should show the local FQDN for the internal IP of the Astaro.



For instance, asssume the hostname of the Astaro in NY were ny01.yourdomain.com, and the Astaro in that location were joined to your local domain, yourdomain.local, as ny01.  You have local DNS resolve ny01.yourdomain.local to the IP of "Internal (Address)" (say that's 172.16.1.1) for the Astaro.  In your WPAD, replace "172.16.1.1" with ny01.yourdomain.local.
