Windows integrated (NTLM) authentication vs Windows integrated (Kerberos)

What is the difference between Windows integrated (NTLM) authentication and Windows integrated (Kerberos)?

How to implement these in IIS6

w.r.t. MSDN

Solution

  • here's a good link:

    http://msdn.microsoft.com/en-us/library/aa480475.aspx

    Also this will show you if kerberos (Negotiate) is on (on your webserver) :

    cscript adsutil.vbs get w3svc/nnn/NTAuthenticationProviders

    NOTE: nnnn is the MetaBase site id

    in the past kerberos has caused me a few problems (when users have too many permissions) resulting in '400 Bad Request' errors
