Is it possible to provide a Link that logs you in as a User when clicking it

Hello,

is it possible to generate a link, that would log you into our Wiki as a pre-existing local account?

We are currently using the LDAP Authentification and from my understanding we could generate such a link with the help of the “Trusted Authentication Framework” and “Headers Trusted Authentication Adapter” but since only one Auth-Service is usable at a time, we can’t use this method because we already use LDAP as our Auth-Service.

So my question is: is there any other way I can provide some people a link into our XWiki that logs them in as a specific user?
