SOLVED: New users not able to login through LDAP

[Giantleap]

I have a Jellyfin 10.8.13 docker instance running with LDAP plugin 1.7 (since 1.8 doesnt save it's settings). All of a sudden, new users that authenticate through LDAP are not able to login. They get an infinite "loading circle". 

Within the Jellyfin I can see that the user authenticates succesfully, and that the new user is shown in the Users page (and shown as active less than a minute ago), but they somehow are not getting logged in. Any tips on how to troubleshoot this? Thanks in advance!

I just tested v18 of the LDAP plugin with Jellyfin 10.8.13 and had no issues saving changes or logging in with a new user.
An infinite loader is typically a sign of an error being thrown, so check the browser console and server logs.

It seems that I had a 13 minute delay. Somehow the baseDN was too wide, so I narrowed it down to a specific OU, and now login is instant again.
