Hello Alvaro

The “no valid certificate available for authentication” error message usually indicates that the client does not have a valid certificate that can be used for authentication. To resolve this issue, you will need to ensure that the client has a valid certificate that meets the requirements of the server. Some things you can check include the following:

- Have you imported the certificate to the user’s computer successfully?
- What kind of error message do you receive on the client’s screen?
- Are there any other indications on the ASA of the attempted connection to ASA?
- Do you get the same output as in the lesson for the `show crypto ca certificates` command?

Now the “Certificate authentication is not enabled” error seems to indicate that certificate-based authentication is not configured or enabled on the device. Here you can check to see if the `ssl trust-point` command is configured correctly.

Let us know your results so that we can help you further.

I hope this has been helpful!

Laz
