Dear All, We are working with an organisation that wish to use NTLM HTTP authenication with Zope. They currently use MSIE and IIS and are able to use the original login credentials supplied when the use logged in to their workstation. So far we have identified two possible routes, both involve using Zope in REMOTE_USER mode (something in front of Zope does then authentication, Zope then does the authorisation based on the REMOTE_USER variable): 1) Use Zope with/behind IIS and use IIS to do the authentication 2) Use Apache in front of Zope and mod_ntlm to do authentication Has anyone else tried this any experiences to report? We have not finalised the server platform yet, so are open to both Windows and unix based solutions, however all being equal we would prefer unix as we may be using certain external libraries (PIL, gd, gs, etc.). -Matt -- Matt Hamilton matth@netsight.co.uk Netsight Internet Solutions, Ltd.
