If you are using an NSS volume to store user data, you must set up the NSS file system trustee rights for the wwwrun Web server user object before restarting your Web server .
Open a terminal console on the server, log in as the root user or equivalent, then enter the following command:
rights -f /media/nss/NSSVOL -r rwfcem trustee wwwrun.ou.o.treename
If the file system trustee rights are not set up properly, you receive the following error message:
An Internal Error has occurred.
