Hi there

I am running Squid 3.0 PRE6 as a reverse proxy for many applications and services. RPC over HTTPS for Exchange/OWA is running fine for a long time. Recently I tried to pass the TS Gateway through Squid, but this is giving me a very hard time. TS Gateway is using RPC over HTTPS just like Exchange does, but I always get an authentication error. Here is what I get:

--
TCP_MISS/401 399 RPC_IN_DATA https://server.domain.com/rpc/rpcproxy.dll? - FIRST_UP_PARENT/server.domain.com text/plain
--

Here is my access rule:
cache_peer server.domain.com parent 443 0 proxy-only no-query originserver front-end-https=on ssl login=PASS sslflags=DONT_VERIFY_PEER

Does anybody run a Terminal Services Gateway (TS Gateway) being proxied through squid? Could there be something wrong with some NTLM passthrough? I am pretty clueless on this, so any help is very appreciated!

I never tested TS Gateway on Squid, but usually Exchange RPC over HTTPS works better using Basic authentication over SSL.

Another thing to verify is the Reverse Proxy SSL certificate: using self signed certificates for Echange RPC over HTTPS, Outlook fails silently if the CA is not trusted.

Thanks a lot!
