I’m setting up a server so that only mapped certificates can get to the webservice. It is set to require SSL/Client certificates, anonymous authentication, asp.net impersonation, forms authentication, and windows authentication are all disabled. One-to-one client certificate mapping is enabled, and certs are set up on the box with an appropriate user mapping. When I try to use the webservice, I get 401.2. If I enable anonymous authentication, it works, but I don’t want any old cert to be able to access the website.
I have another machine that has anonymous authentication disabled in this configuration, and it works. I’m not sure what the difference is.
The problem ended up being the software that was calling in, not in the configuration. I’m awarding natemrice the bounty since he put in a good effort to answer what ended up being a non-question.
edit: For more information, it actually ended up being a mismatch between the cert being sent (from the local box) and the cert that was put in the oneToOne mappings. The common name was the same, but the certs were different (likely the first one expired) so the cert simply wasn’t authorized.
