Yes, we'd like to have this permanent... for the time being, so as not to stop users from experimenting with it,

I think it would be nice to discuss this in a short meeting

I thought I had given a further reply already - sorry for the delay.

We do use other entry points - at the moment one, but there are supposed to be more. For the one in question already used, a logout works

@aclassen The normal behavior should be that when you arrive on the login page while you had an SSO ticket already (from Keycloak for example) you are automatically login into GoFAST, so you don't have to login form displayed at all. If you are an external user (and no SSO), you will have the form displayed.
I hope this answer your question.

Je rajoute également un lien sur le problème de popup d'authentification lors de l'ouverture d'Office cité chez Microsoft : https://support.microsoft.com/en-gb/help/2019105/authentication-requests-when-you-open-office-documents

Aucune des solutions ne nous semblent convenables malheureusement.

Pour information le problème n'existe pas avec OnlyOffice (et LibreOffice de mémoire)
