Opened: Nov 22, 2016 Severity: 3-Major
With SWG client side NTLM auth configuration while doing the NTLM auth for backend, ECA plugin is trapping the Authorization credentials (NTLMSSP_NEGOTIATE) sent by the client, it sinks the request and generates the 407 to the client to do proxy authentication.
Backend server access is restricted.
Set-up SWG for auth with ntlm credentials Access a proxied resource which also requires ntlm auth
None
Now when using SWG in explicit proxy mode with NTLM authentication with the Proxy-Authenticate header, BIG-IP allows NTLM authentication to proceed simultaneously to protected resource servers that also use NTLM authentication with the Authenticate header.
