Multiple issues around logging in with LDAP enabled

[surfrock66]

Problem description

I have LDAP enabled for auth on my airsonic and it mostly works. If I am on a device and log in with an account, it's fine. If I then try to log out then log in with a different account, in the web browser I receive a "403 Forbidden" error, and if I try to use an app (DSub on Android) I can log in fine with the first account, the second account says "Wrong username or password" even though I can open the browser and log in with the second account credentials just fine. Going back to the web browser on a computer, if I use incognito windows, I can log in with any account successfully.

It appears that from any device/api, you can only log in with one account, then something is stored/cached that prevents authentication or authorization from a second account even after logout.

I have an account for myself and a separate account for my daughter with access to different libraries, and it would be nice to be able to context switch by switching accounts on the same device.

Steps to reproduce

Describe how somebody else could observe the same behavior you do. If possible,
include relevant configuration or files that cause the problem. If sharing media
files, ensure you are legally permitted to share copies!

1. Log in successfully to airsonic in the web browser.
2. Log out in the web browser.
3. Log in with a second account. You will receive a 403 forbidden error.
4. Open an incognito window and log in with the second account, it will be successful.

Additional Notes

I am using openLDAP server, slapd, on the same box. I see nothing in the airsonic logs showing the failed auth or an issue with ldap. I do get the following log entry from slapd during the error:

slapd[2982687]: <= mdb_equality_candidates: (uniqueMember) not indexed

But that's hardly descriptive.
