Description (partial)

Symptom:
Document ALL extensions of certificates are supported by ASA and checks performed by ASA on client certificate received by it. We do not have it documented. 

We have seen cases where customers are renewing certificates and ASA is rejecting it. We do not know the reason for it and debugs are not very helpful.

A document of what all certificates extensions are checked and what additional checks are performed when client certificate is presented would be helpful for customers as well as TAC engineers.

Conditions:
ASA performing client authentication.
