In order to change to remove the prefix for a different virtual proxy to use another authentication method by default:
in the QMC, go to "Virtual proxies" > "Central proxy (default)"
Modify the virtual proxy prefix to the desired string
Click "Apply" in order to save
Go back to "Virtual proxies", double-click on the virtual proxy that you want to make default in order to edit it.
Remove the virtual proxy prefix
Click "Apply" in order to save
Note: If the virtual proxy made default is using SAML authentication, the SAML Assertion Consumer Service URL will also need to be updated in the Identity Provider configuration.
This isn't working for me. I have an environment with two machines where we configured oidc-authentication by adding a new v-proxy with a prefix. It will load balance to both machines and is linked to both proxy-services. All three v-proxies have unique cookie names.
When adding a prefix to the two initial default v-proxies and removing the prefix from the newly created oidc-v-proxy the checkmark for "default" is checked and dimmed. The v-proxy overview is also showing Yes for the initial default and No for the v-proxy w.o. a prefix. The dimmed checkbox indicate that it has a function but it can't be unchecked and it is missing for any new v-proxy. Bug or WAD?
