  • 1.  Diference between NTLM (HTTP 401) & NTLM (HTTP 407)

    Posted Sep 13, 2012 08:09 AM

    Hi All

    The goal is to configure ntlm authentication.Configured web gateway in inline + proxy (block mode),configured ntlm authentication in web gateway.Testing LDAP is successful,testing NTLM (HTTP 407) is successful,only when testing NTLM (HTTP 401) returns "unable to reach domain controller".

    Set up authentication policy to enforce authentication,when going thgorugh the web gateway proxy transparent authentication occurs,no problems while surfing,url filtering works perfect.When not using the proxy sometimes a dialog box appears that DOES NOT accept user name & password !!! (proxy refused the connection)

    Any guidence is appreciated

    407 is used in proxy mode

    401 is used in inline mode.

    Hi Ben

     

    Thanks for the reply.I have another question regarding the post.NTLM v 2 is only supported when using the proxy 407 and when inline only ntlm v1 is supported,am i correct or am i wrong?

     

    It might be that in my sitation only NTLM v 2 authentication i supported via group policy?

    Correct.

    NTLM v2 will be used with (proxy mode). Inline mode will need NTLM v1 enabled.

    Windows vista, 7, and 2008 by default do not allow NTLM v1.
