Hi, I am trying to set up zope on a RedHat box, so that anyone in the 'zopemaster' unix group can install files (like zexp, external methods, products). Zope is run by the 'www' user, which is in the 'zopemaster' group. The UID has been set as 'www' in the z2.py file. Now, when I install a file as another user in the import directory, I set the group of the file to zopemaster, and set the permissions to g+r, zope cannot read them, and complains about a permissions problem. When the file is o+r, it works. For testing purposes, I exported a file from zope, and the group of the file was 'users'. I tried to modify the z2.py file by adding the line os.setgid(115) to the z2.py file (where 115 is the gid of 'zopemaster'), but it didn't help. Any ideas? Thanks, Stefan.
