Using Kee 184.108.40.206, Firefox 59.0.3 (64-bit), Windows 7 (64-bit), KeePass 2.38 and KeePassRPC 1.8
Since updating to Kee 2.0 on Firefox 57, automatic login using sites using HTTP-auth has never worked for me and is still not working to this day.
Unlike questions like Basic auth not filled correctly (Kee 220.127.116.11 Ubuntu 56.0 64bit) and Priorities with HTTP basic auth this issue is definitely not caused by an incorrect domain configuration. They worked fine in FF56 and the old KeeFox extension. Additionally, Kee correctly finds the single login associated with the sites and lets me pick it in the dialog…
However, when choosing that login, I am still presented with a standard Firefox authentication prompt that’s empty.
The same thing occurs when ticking the option “When Kee finds only one matching network login (e.g. HTTP Auth), automatically login” in Kee’s options page. No Kee dialog is shown, but I still get the prompt.
I’ve tried updating KeePassRPC, uninstalling and reinstalling Kee. What’s even stranger is that this works correctly on another machine using the same OS and Firefox version.
Do you think it could be something to do with my company’s corporate proxy settings? Firefox is set to “Use system proxy settings”. This corporate proxy requires a username and password of its own, and sometimes Firefox sees ‘407 Authentication Required’ responses for requests while subsequent requests will work correctly. Perhaps Kee cannot cope with this. What else can I do to diagnose the issue, and if it turns out to be the proxy, could you perhaps implement a workaround for it in future?
