I have an Apache instance that's configured to use KerberosOrBasic authentication. Virtually all the users are Windows users on the LAN and they connect using Kerberos. I have one Linux user who is connecting via VPN. He should be getting a login prompt, but it goes immediately to: '''Authorization Required Unauthorized - authentication failed. ''' It appears Apache is sending to correct response, but FF isn't prompting for login. Is there some browser config required? TIA
