Hello. I've been banging my head against the wall for the past two days. I have the LDAP plugin working for authentication and lookup. It woks fine for authentication and it will find the users when adding a user to a new ticket (showing them as remote). However, it stopped autofilling the email and name when the remote users are clicked. The dropdown box just disappears. When this happens, there's a 404 (Not Found) error logged to the browser console.

I've seen several threads with similar issues but I'm not finding a solution. I haven't changes recently that I can think of. It's been working flawlessly for years. I tried downgrading PHP from 8.1 to 8.0. In the other threads, there's recommendations on changing the backend for users to ldap.client.pXiY. I fixed that but this isn't really an authentication issue. Almost none of my users actually sign in, it's all done via email from their perspective so I feel like I'm barking up the wrong tree.
There was another thread where the person had commas in their AD names but I don't have that. We do have periods in some but I get the same problem with AD names that don't have a period. Same thing where someone had issues with accounts that were nested too deep in AD. That doesn't seem to be the case with my server.

Any assistance would be greatly appreciated. Thanks!
