Re: HTTP probe with 401 NTLM-based HTTP authentication

Hi Surya,

Just FYI - We have a magical perl script that can do this for you on the NetScalers. It's currently being entered into the support knowledge base, but if you need it now just contact support and mention this thread. I've given them a heads up you'd be calling.

Thanks,
Tal

Subject: [load balancing] HTTP probe with 401 NTLM-based HTTP authentication

Hello the ML.

I have to configure a cluster of NetScalers (but the question is open to other vendors also ;-) ) to load balance HTTP-based Sharepoint web servers, and it uses an NTLM challenged-based user authentication.

I can solve the problem with basic http auth. by sending an additionnal header with the login:password pair encoded in base-64, but what about using the challenge in NTLM mechanism ?

Does anyone know if any load balancer on the market is able to send HTTP probe when using NTLM auth on the back end servers ?

Otherwise I'll have to ask dev. to create a specific page available without any authentication.

regards,

Surya<mailto:%[email protected]>
