Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/119.0

Steps to reproduce:

In our intranet environment (active directory) we use kerberos to authenticate users on web applications, including API-Calls via JavaScript.
Since Firefox version 118 the authentication on API-Calls is not working anymore.

Client-OS: Windows 10 x64
Firefox-Version: 118.0 and higher
User-Agent-String: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/118.0

Actual results:

The following configuration settings are being applied via group policies to enable sso via kerberos:
network.negotiate-auth.allow-non-fqdn -> true
network.negotiate-auth.allow-proxies -> true
network.negotiate-auth.trusted-uris -> relevant intranet uris (comma separated)
network.negotiate-auth.delegation-uris -> relevant intranet uris (comma separated)

Kerberos auth works on the site itself, but API-Calls via JavaScript are not being authenticated anymore.

Expected results:

Before version 118.0 the mentioned settings ensured a working sso via Kerberos.
The expected result would be, that sso authentication is working on all kind of request types.

This report appears to be a duplicate of bug 1855650, which is a regression of bug 580353. Lacking a manageable reproduction I cannot prove that these bugs (1855417 and 1855650) are indeed duplicates, but the coincidence of their occurrence is evidence enough.

This comment states the plan of the developers to back out the implementation in bug 580353 until a better solution is found. This issue should stop reproducing in the coming Nightly builds. If it still occurs after the backout, this could be a different issue.

Can you confirm that this issue no longer occurs in next week's Nightly v120.0a1 from 2023-11-02?

Thank you for your contribution!
