AmzingDominik, in a perfect world I would agree with you. However in the real world this is not allways possible.
The organization I work for has spent a great deal of cash to purchase thousands of GetAccess licenses so that our Domino web servers use NT authentication.
Unfortunately, our version of GetAccess is not compatible with Domino versions greater than 5.0.9a. Until there is a corporate need or desire to spend more money to replace those licenses that work, installing the latest full version will not be possible if we want to use the most current, compatible version.
I suspect there are many other Domino administrators out there who are in similar circumstances.
