I implemented dimension security and got it to work successfully in the test
environment. However, when I implemented the same solution in the production
environment it fails, I receive this error message when testing the role:

User-generated error - the dimension "Employees" has no valid member.

The difference between these two environments, they are both on a separate
network. I can't determine why it works in the test and not production. The
only thing I can think of is that the domain/username that UserName function
is not matching the domain/username that I have in the table but it is the
same as in the test environment.

Is there a way to verify what the Username function is returning so I can
check the comparison?
