In the project I am working on, the client would like to authenticate Smart Cards that have a certificate with a value in subjectAltName that is not a UPN. The value will be an alphanumeric GUID@mydomain.com format. For example: 1891ADDA010@MYFIRM.ORG
How can AD be configured to do a one-to-one mapping based on this value in this X.509 certificate attribute?
From what I have read in all the KB articles AD requires a UPN in the subjectAltName for locating the user. The client is not happy about having to update that certificate with a UPN, as this would be solution specific to AD. Other directories such as eDirectory do not have this requirement.
Has anyone found a way around this restriction for AD and is it MS supported?
Thanks in advance!!
