Opened: Dec 04, 2014
Severity: 3-Major

Symptoms

When a response-adapt profile is applied to a virtual server, the BIG-IP system sends a FIN to terminate the connection to the server/client before NTLM authentication is fully negotiated, causing NTLM authentication to fail.

Impact

NTLM authentication does not work.

Conditions

A virtual server configured for NTLM authentication that uses a response-adapt profile.

Workaround

None.

Fix Information

NTLM authentication now works on a virtual server with a response-adapt profile.
