A question on TREX Web Repository Manager crawler for NTLM IIS sites

We have a lot of Intranet web sites running Integrated Windows Authentication (NTLM) as the security manager. However, I was told by SAP people that the crawler (which craw the web pages through the Web Repository Manager in EP) does not support NTLM authenticated web site. Is there any workarounds that we can do to allow the crawler to access the web pages? Since we want to provide a Federated search service for our users to perform a single search for all of our Intranets.

    The problem with NTLM is that Microsoft hasn't documented it. So there is no legal way to find out, how a third party component (like the Web Repository Manager) can authenticate itself using NTLM.

    There are some documents availabe on the web about this topic but the content of these was obtained by reverse engineering Microsoft's products, which is illegal respective to the license agreement.

    Hence I don't see a chance for support of that authentication scheme.

      Officially Basic and Digest Authentication are supported by the web repository manager. However in Ep50 SP6 and all EP60 releases, it might be worth a try to configure a web repository against an NTLM-only IIS.

      As to access rights: the web repository does all operations in the name of the mapped user, even cache lookups. So, if there is a standard user configured in the landscape system, that user is used for all requests, independant of the portal user. If there is no standard user and authentication is required by the remote server, the portal user mapping is asked for the credentials to be used against the server. If no credentials exist, access is denied.
