It's going to check at least 2 things:

 

  1. Certificate validity, which includes X.509 structure and constraints, and validity times

     

  2. Trust, which must be established from the client cert all the way up to the self-signed root CA. In (I believe) 11.4 and above, the client SSL profile has that ability to consume subordinates (but not the root) from the handshake in order to assist in building the chain, but otherwise the Trusted Certificate Authorities "bundle" must contain the root and every subordinate in the chain path.

     

A third and optional validation is revocation status, which would come from a CRL.
