Hello,
When trying to authenticate with active directory on our Konica Minolta Bizhub C224, we get the error "Authentication Failure" on the control panel and "Authentication failed.[User Authentication]" in the web connection. The settings appear to be correct. We are able to authenticate just fine with NTLM v2, but the machine doesn't grab the user's email address when using this method. When the machine was installed, we were able to authenticate fine with AD, but then it suddenly stopped working. The installer was unable to fix it. Any ideas?
