Following up on the previous trouble ticket, I updated to Virtualmin 3.57, and attempted to install the Turba script on one of my virtual servers that I had not attempted the installation on previously. Upon doing so I get the following:

Configuring Apache PHP settings ..
.. already done.
Now installing Turba version h3-2.1.7 ..
Failed to run database setup script : ERROR 1142 (42000) at line 35: SELECT,INSERT,UP command denied to user 'usb'@'localhost' for table 'turba_objects' .
.. failed! See the error message above for the reason why.

I attempted to install another Horde child program - nag - and that installed just fine.
Logging into Horde on the virtual server as the Administrative user seems to allow me to configure the module, but I am unsure if the module is functioning correctly as the database setup script was unable to finish.
