How to publish RD Web & Gateway (2008 r2) on ISA 2006, and still have time to watch The Big Bang Theory!

So I was asked the question, how do You publish the new Windows Server 2008 and 2008 R2 editions of Terminal Server, including the RD Web and RD Gateway (GW) services. And on top of that still use the ISA 2006 as authentication with Forms Based Authentication (needed in this case for RSA keys). Sounds easy enough right? Wrong!

Well once You get your head wrapped around the limitations, which of course are always hard to find documentation on, then it is easy enough. Basicly the RD Web service is easy enough to get working, simple next next next, will get You there with little trouble.(The RD Gateway on the other hand…)

Configure a ISA 2006 rule, with relevant web listener (or existing if appropiate), allow the /rdweb/* paths, use FBA authentication, use NTLM delegation of authentication to the internal webserver, configure the webserver (RD WEB) to use NTLM, install relevant SSL certificates to ISA and webserver, and presto it works! It even works with SSO if needed, and the user is only prompted by the ISA forms and not a second time by the RD Web site.

So far so good! A small hint before we go on, if You want to add multiple connections to other Terminal Servers in the RD Website, Read the rest of this entry »

How to install a SSL certificate backup file on Exchange 2007 and still have time for facebook

The easiest way (I love easy!) to order and install an SSL certificate on Exchange 2007, is to order a SAN (Subject Alternative Name) certificate with AutoCSR meaning you dont have to create a CSR but instead get a certificate backup file (PKCS#12, P12. PFX). You also save time with the SAN because you only use one certificate for all services and can move services from one domain to another in the certificate with no problems.

Make sure you get a SAN certificate including the full domain name(s) you use to access Outlook Web Access, Outlook Anywhere, Autodiscover and any internal servernames using the certificate (usually free).

The Certificate you order should contain something like this:

  • mail.sole.dk and/or owa.sole.dk – for Outlook Web Access
  • autodiscover.sole.dk and any other e-mail domain you use with Autodiscover/OA.
  • MYSERVER01 and MyServer01.domain.local¬†– and any other internal servername that will be using the certificate

Personally I setup servers to respond only to OWA and ActiveSync on the mail./owa. domain, and use all other services like Outlook Anywhere, etc. on the autodiscover. address, this way I can use Forms Based Authentication/Basic with my OWA/ActiveSync website, and NTLM with my other services. You can see more information about this from my previous blogs here. Some people argue for and against having internal server names in the certificate, but I figure if they are free anyways, and might help why not add them – and if security is so much an issue that internal server names must not be revealed, you have other much bigger problems anyway.

Now some simple commands to manipulate Exchange 2007 SSL certificates. (Stolen from the danish Exchange 2007 guide on FairSSL, I co-authored the manual) Read the rest of this entry »

How to configure ISA 2006 with FBA for OWA and NTLM for Outlook Anywhere and Autodiscover in Exchange 2007

Configuration of Exchange 2007 with Outlook Web Access (OWA), Outlook Anywhere (OA), ActiveSync and Autodiscover can add grey hair to any system administrator or IT consultant. Then also trying to get different authentication schemes and ISA 2006 to play nice is not making it any easier.

Most Administrators have a wish to configure their environments used externally as securely as possible, including using SSL certificates with HTTPS instead of no encryption with HTTP, and using NTLM authentication instead of Basic authentication. But security is not everything, a userfriendly interface like Forms Based Authentication (FBA) is a must to avoid user iritation and support calls.

However getting FBA and NTLM to work together in ISA with Exchange 2007 can be quite scary, so lets go deeper and find out what we need to be aware of to get it working.

How to publish a website with both Anonymous and Forms Based Authentication in ISA 2006

We had a customer asking for the main part of their Sharepoint website to be accessible from the public with anonymous access, and still have a part of the website require authentication thru Forms Based Authentication (FBA) in ISA 2006 firewall. Since ISA can only have one listener on a website, and the authentication is set on the listener, this was a little bit tricky to solve.

The solution however is extremely simple and I hope this little bit of information will save someone else some time. Read the rest of this entry »
