F5 Sharepoint Auth

Hi

 

We have sharepoint sites that where behind a TGM with "No delegation, and client cannot authenticate directly" when users accessed the site externally. Now the sites are behind the F5 they get prompted for Authentication. Is there away this can be blocked like the TMG did?

 

Thanks

    If you explain what the TMG was doing, yes we I explain how to achieve that with F5. Also, post part of the F5 configuration, so we understand what is configured.

    Hi,

     

    when you are prompted, there is a HTTP 401 response.

     

    Can you look with your browser developper tool (F12) what is the value of WWW-authenticate header?

     

    it seems it is Negotiate (header value for Kerberos authentication)

     

    Is the VS IP using the previous TMG IP? if not, can you do a reverse DNS lookup of the TMG IP, then try to create a DNS reverse entry of this IP with the same value than TMG.
