Hello, I would be very pleased if anyone could give me some help with the following problem. I tried to use the SSL Cert Auth product to do SSL client authentication on a Windows 2000 machine. It works fine on a Windows 2000 pro machine, but fails on a Windows 2000 Server machine. The error message I get is the following: Traceback (most recent call last): File "C:\PROGRA~1\PKIINT~1\lib\python\OFS\Application.py", line 552, in import_product product=__import__(pname, global_dict, global_dict, silly) File "C:\PROGRA~1\PKIINT~1\lib\python\Products\SSLCertAuth\__init__.py", line 1, in ? import SSLCertAuth File "C:\PROGRA~1\PKIINT~1\lib\python\Products\SSLCertAuth\SSLCertAuth.py", line 31, in ? class SSLCertAuth(PropertyManager, SimpleItem): File "C:\PROGRA~1\PKIINT~1\lib\python\Products\SSLCertAuth\SSLCertAuth.py", line 38, in SSLCertAuth ViewManagementScreens = AccessControl.Permissions.view_management_screens AttributeError: 'AccessControl' module has no attribute 'Permissions' Any ideas?
