Our users log into our instance using SSO. But, we will have a small number of guests who will need to use local, non-federated accounts. I'm aware of the option to enable mixed-mode authentication, but because our number of guests will be very limited I do not want to use the dual log-in page. Is it possible to just direct these guests to a different URL for form-based login (just as the admin account can login by going to xxxx.com/admin)?
Reviewing through your description above you have outlined the currently options available for non-federated accounts to access your instance. That being said, if you are interested in seeing an additional login feature added into a future release of the Jive platform, I would suggest submitting an idea to the Ideas for Jive space where our Product team reviews through top rated ideas when considering features for future releases of the platform.
