How can you revoke a client certificate with Eventgrid MQTT broker

Question

I have created an MQTT enabled namespace in event grid and uploaded self signed CA certificate for client authentication. However, if i want to revoke one of the client certificates, I did not see an option for that.

If the service does not support this, then other option would be through a CRL distribution point. I tried hosting crl and add the url in signed certificates from this CA but still connection was succeeding for a revoked certificate.

Is there any way to achieve this?

Also any sdk support for this broker feature?

Hello @Rini Varghese SA ,

welcome to this moderated Azure community forum.

Azure EventGrid support for MQTT offers the option to disable users for connecting to the broker.

Just switch the connection status and save the page:

Is this a solution for your need to disable individual clients?
