>Of course systems administrators MUST instruct their users what to do when they see this message. Problem is: any security measure that depends on user actions - will fail. For high security environments there should be an option to simply deny access to sites that have some problems with certificates. Vasily
How fun! I linked to this on last weekend's weekly roundup and am just now getting around to letting you know. (I guess we were busy celebrating Easter!) Thanks so much for sharing!
Ok, I'll check TechNet again. Probably this is the case.
Vadims, generally good article but I think you misunderstand the purpose of EDITF_ATTRIBUTESUBJECTALTNAME2. This flag allows a user to submit a request to the CA with specifying additional attributes containing a SAN. This is actually a very sensitive operation and not recommended to be turned on. You really only want to do this if your templates require manager approval. You should not need to turn this flag on if the certificate request itself contains the SAN extension.
Unfortunately there is no such option. There is setting that will permanently block connection to a HTTPS web site with invalid certificate, but not for mentioned case.
