My subversion repository requires both a https client cert as well as subversion username/password.

Unfortunately, the jenkins subversion authentication config presents a radio button to select one of: username/password, SSH public key, HTTPS client cert.

I have tried to work around this by modifying the .subverion/servers file to specify the name of my pkcs#12 file and the password/passphrase for it, and then select the username/password radio button. But unfortunately, I can't seem to get it to work.
