Hello, I´d like to add an additional field to the login screen. The field should be a select option (at least that is the html I would use, regardless of how it is generated) and ideally the field can be prepopulated via the url (subject to available options).
I assume something like this can be done via an authentication extension and I already have one, but so far it does not add the additional field, nor is clear to me, how to make any additional UI element depend on configuration or backend information. At least https://guacamole.apache.org/doc/gug/guacamole-ext.html#updating-existing-html addresses only static html changes. Does anybody have a working example, how-to, or similar? Thanks, Joachim
