I'm surprised you got this working in 8.9 at all. Did you get a password promt from Solr (admin UI password page) or from the browser (simple popup with user/pass fields)?
Problem is, if you have not enabled Solr's BasicAuth plugin, then NginX will send the "Www-Authenticate Basic" header on any request without credentials. This will trigger your browser to pop up the login prompt. Even if the browser remembers your credentials for the initial HTTP GET request to load the Admin UI, all the small XmlHTTP/Ajax requests done by the Admin UI's JS will not pass this credential to NginX/Solr, and NginX will likely respond to browser with a 401 and new WWW-Authenticate headers. I'm not aware of a change between 8.9 and 8.11 that would change this. > 10. aug. 2022 kl. 12:48 skrev save-cho...@hotmail.com: > > Hey Jan, > > thanks for your reply > >> The Admin UI will send Ajax requests to Solr and to do that it needs the >> basic auth credentials. >> With Solr's built-in Auth, Admin UI will remember the creds and explicitly >> pass them on every Ajax request. >> But for 3rd party auth in nginx, Admin UI will be able to do that. > > And this must have been a "recent" change in > functionality, since it behaved differently before > version 8.10.0, is that correct?
