Appendix – Client Authentication

Client authentication feature enables providing a client certificate over secured connections (HTTPS) when using UFM REST API, and associating a specific SAN (Subject Alternative Name) of the client certificate to a UFM user.

1. Configure HTTPS access with UFM web client authentication using the command ufm web-client mode https-client-authentication

2. Associate client certificate SAN with a UFM user using the command ufm web-client associate-user

3. Set a server certificate hostname used to access the UFM web client using the command ufm web-client server-cert hostname

4. Configure certificates automatic refresh settings using the commands:

   1. ufm web-client client-authentication cert-refresh self-client-cert fetch for supplying a bootstrap certificate file

   2. ufm web-client client-authentication cert-refresh ca-cert for setting a download URL for root/intermediate certificate

   3. ufm web-client client-authentication cert-refresh server-cert for setting a download URL for server and bootstrap certificates

   4. ufm web-client client-authentication cert-refresh enable for enabling UFM web client certificates auto-refresh

Notes:

• You may refresh the server and root/intermediate certificates manually using the CLI command ufm web-client client-authentication cert-refresh run-now

• Instead of using the automatic refresh, you may supply the server and root/intermediate certificates using the commands ufm web-client server-cert fetch and ufm web-client client-authentication ca-cert fetch

To review the settings, run the show ufm web-client command.

Example:

            

            
ufmapl [ mgmt-ha-active ] (config) # show ufm web-client
