Using NTLM to identify Network users?


We are on a Windows network and I am writing a BSP application in which I want to identify the Windows user who is accessing the page. I don't need to authenticate the user, but I would like his Network logon ID. I believe that I can somehow obtain this, as the network ID must be passed along with the browser for NTLM authentication. Does anyone know how to do this?

Thanks and Regards,

Martin Ceronio

    Hmmm...Neelan posts and signs with Martin.

    Are you sure that NTLM authentication is used? As far as I know, this is not supported for WebAS.

    Then afterwards you can tell us exactly what you saw in the HTTP headers. I suspect Basic Authentication.

    I wonder whether the Windows userid will not be the same as WebAS userid? Is not sy-uname what you want? Probably not.

      Why not create your own! It will only cost you 5 minutes of time. And even we profit with a new user!

      Interesting. Yes, some parts of the work should be relatively easy to implement as ICF handler. However, quickly scanning that link shows also things such as des algorithm, etc. This might become difficult. But, there is nothing like a good challenge!

      Let us know how it turns out. (Once you have your one userid, you could even write a nice weblog:).

      Looks good. At the moment there seems to be many of them. In our group we use a different product, maybe one day I will write about our experiences with it.
