Upon receiving client certificate, BIG-IP will go through this list of CAs and confirm client's identity. We should add to Trusted Certificate Authorities a single certificate file (*.crt) with one CA or concatenated file with 2 or more CAs with the purpose of validating client certificate, i.e. Adding CA file to Trusted Certificate Authorities Optionally setting the Frequency of such checks if we don't want to stick to the defaults.Enforcing Client Certificate validation by setting Client Certificate option on BIG-IP to require.Optionally adding same CA that signed client certificate to Advertised Certificate Authorities.Adding a CA file to Trusted Certificate Authorities ( ca-file in tmsh) to validate client certificate.The way to do this is to configure BIG-IP by: However, such credentials are in the form of a client certificate. How to Configure Client Certificate Authentication on Client SSL profileĮssentially, what we're doing here is making BIG-IP verify client's credentials before allowing the TLS handshake to proceed. The Topologyįor reference so we can follow Wireshark output: This article is about the client side of BIG-IP (Client SL profile) authenticating a client connecting to BIG-IP. In this article, I'm going to explain how SSL client certificate authentication works on BIG-IP and explain what actually happens during client authentication as in-depth as I can, showing the TLS headers on Wireshark.
