Hello Viktor,

Sorry, I did not mean to upset you.

Somehow I seem to have misunderstood something.

The CAPF certificate is the CA certificate he goes for? 
Cisco states that this certificate requires both CA and the extended key "TLS Web Server Authentification"?

Viktor, can you please write me directly??

Robert

YOU DO NOT need to change the Cisco implementation.

Nothing Cisco is telling you requires your issuing CA to have an extended key usage listing just "TLS Web Server Authentication".

Your problem is a misconfigured CA certificate.  Make sure your *CA* certificate has no extended key usage specified, OR has *all* the key usages specified that are required by any leaf certificate it will issue.

The extended key usages on the CA are interpreted to LIMIT the key usages of certificates it can issue.  You can certainly use this extension, but then expect the CA to be invalid for key usages you did not list.

"Correct" is in the eye of the beholder.  The RFC5280 alternative to using the extended key usage (X.509 policy) is a complex mess.  Many implementations do the sensible thing and overload the extended key usage instead.  OpenSSL is among these and this is unlikely to change.
