I am trying to enable mutual authentication for my WebService hosted in IIS7. I have the server side cert setup and working but cannot figure out how to get a Certificate Trust List created and setup in IIS7 so that I can require and validate client side certificates.
All of my client side certs are signed by my own root cert so I need to create a CTL that contains just my root cert and then have IIS validate client provided certs against the CTL.
Can anyone shed some light on how to do this? IIS6 had a UI for assigning a CTL, but I can find nothing similar in IIS7.
Update:
I have now successfully used MakeCTL in wizard mode to create a CTL with a Friendly Name. However I don't have adsutil support on my IIS7 box so via other posts elsewhere I am trying to use the 'netsh http add sslcert' command to assign the CTL to my site.
Before I could use this command I had to remove the existing SSL cert that was assigned to my site for server authentication. Then in my netsh command I specify the thumbprint of that very same SSL cert I removed, plus a made up appid, plus 'sslctlidentifier=MyCTL sslctlstorename=CA'. The resulting command is:
netsh http add sslcert ipport=10.10.10.10:443 certhash=adfdffa988bb50736b8e58a54c1eac26ed005050 appid={ffc3e181-e14b-4a21-b022-59fc669b09ff} sslctlidentifier=MyCTL sslctlstorename=CA
(the IP addr is munged), but I am getting this error:
SSL Certificate add failed, Error: 1312 A specified logon session does not exist. It may already have been terminated.
I am sure the error is related to the CTL options because if I remove them it works (though no CTL is assigned of course).
Can anyone help me take this last step and make this work?
UPDATE 01-07-2010:
I never resolved this with IIS 7.0 and have since migrated our app to IIS 7.5 and am giving this another try. Per the response from Taras Chuhay I installed IIS6 Compatibility on my test server and tried the steps he documented using adsutil.vbs (which can also be found here). I immediately ran into this error:
ErrNumber: -2147023584 Error trying to SET the Property: SslCtlIdentifier
when running this command:
adsutil.vbs set w3svc/1/SslCtlIdentifier MyFriendlyName
I then went on to try the next adsutil.vbs command documented and it failed with the same error.
I have verified that the CTL I created has a Friendly Name of MyFriendlyName and that it exists in the 'Intermediate Certification Authorities\Certificate Trust List' store of LocalComputer.
So once again I am at a dead standstill. I don't know what else to try. Has anyone ever gotten CTL's to work with IIS7 or 7.5? Ever? Am I beating a DEAD horse. Google turns up nothing but my own posts and other similar stories.
Update 2/23/10 - I've confirmed with Microsoft that this is a bug with IIS 7.5, but it does work with IIS 7. Check out this link for details: http://viisual.net/configuration/IIS7-CTLs.htm
Update 6/08/10 - I can now confirm that KB981506 resolves this issue. There is a patch associated with this KB that must be applied to Server 2008 R2 machines to enable this functionality. Once that is installed all works flawlessly for me.
