Hello, This question has been asked several times already, and the answer is always the same: Q: How to to interface Zope with IIS A: turn off challenge/response authentication and turn on basic authentication for Zope to handle authentication *BUT* I want IIS to handle authentication, and give Zope the user's name through REMOTE_USER. It seems not to be possible. Has anyone managed to do that? Here, everyone who is logged on the NT Domain is already authenticated when they browse the intranet. But I don't know how to get this information from Zope. *Please* give me any clue concerning this. <PROMISE> If someone can point me in the right direction, I can even start to write some code because my boss is not willing to use basic authentication. </PROMISE> Regards, Jephte CLAIN minf7@educ.univ-reunion.fr PS: please CC any answer to minf7@educ.univ-reunion.fr
