As you can read in z2.py : # User id to run ZServer as. Note that this only works under Unix, and if # ZServer is started by root. UID='nobody' This is not effective on NT server. Thus, could somebody tell me Howto to start Zope as 'root', choose the UID when zope switches identity to a user specified at installation. I suppose with your answer I should be capable to 'mount' a NT network volume in Zope with LocalFS. Cheers, FR.
