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. 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 any other server that will be using the certificate

Personally I setup servers to respond only to OWA on the mail./owa. domain, and use all other services like Outlook Anywhere, ActiveSync, etc. on the autodiscover. address, this way I can use Forms Based Authentication with my OWA website, and NTLM with my other services. 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 a danish SSL certificate reseller – thanks!) Read the rest of this entry »

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.

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 »
