An excerpt from the above mentioned TID:
"Additionally, the workstation policy package has the ability to perform
loopback support. This means that the Workstation Package settings can
either take precedence over the User Package settings, or ignore the User
Package settings, or be overwritten by the User Package settings. The
default is for the User Package to have precedence over the User Package
settings. These settings need to be confirmed that they are correct
according to what the customer wishes are."

Which takes precedence?
