Mac OS X Server version 10.5: Group Web services not available after upgrade from 10.4

Issue or symptom

After an upgrade from Mac OS X Server version 10.4 to Mac OS X Server version 10.5, site-specific Web services are not accessible for the default website. Server Admin Web shows the Services for Groups checkboxes in an indeterminate state (with a "-" in the checkboxes instead of a check mark).

Solution

1. In Server Admin, select the Web Service.
2. Click the Sites tab.
3. Select the default site from the list.
4. Click the Web Services tab.
5. Click the desired Web service checkboxes (once to disable, twice to enable).
6. Click the Save button.
