SOLVED Problem with App Passwords
I just noticed that I cannot create new App Passwords for regular LDAP login anymore. When I go to the App Passwords thing, the drop down menu only allows me to create an app password for SFTP connections and for the Mail server, not for "normal" apps anymore.
I am not sure since when, could be since the latest Cloudron version (I'm on v6.0.1), or since I added a few apps. I tested for multiple user accounts on my cloudron, and on multiple browsers.
Of course, I am available if any debugging steps are needed, or any more information.
@mehdi Indeed this was a regression, this is fixed now in 6.1
