Windows client authentication certificate

For more information, see Enabling Authentication for a Library Application. If this is the case, you need to impersonate the client so that the client's identity is propagated downstream. For detailed information about impersonation, see Client Impersonation and Delegation. For a discussion of issues involved in deciding whether to do authentication at the data tier, see Multi-Tier Application Security. Client Impersonation and Delegation. Library Application Security.

I always see such along with in IIS log files for client certificate authentication. So it is not a problem :.

These distinguished names may specify a desired distinguished name for a root CA or for a subordinate CA; thus, this message can be used to describe known roots as well as a desired authorization space.

This makes the communicating parties incompatible on certain occasions. Both the implementations are debatable. On one hand the list sent by the server cannot exceed a certain limit on windows the size is 12, bytes. If exceeded, the auth will fail. On the other hand, the Intermediate CA names are readily available in the client certificate provided by the user, so it makes it easier during the certificate chain validation, therefore some systems prefer this over the previous one.

Both have their own merits. As a result the authentication fails as the client is unable to provide a client certificate to the server.
