VSI NFS LUN error

I don't know if this is a functional error or not.  In the VI client, When looking at the properties of the NFS LUN, the VM's show the error "Unable to display Properties: The DHSM username or password is invalid for File Storage System".

I have checked on the system and the username and Password I set up for the DHSM when installing the plugin is there, and the service is running.  There were no errors when installing the plugin.  Has any one else run into this message?
