Did you ever get a resolution to this? I too would like to be able to pass authentication via vmware-rc command line. Though -u -p are supposed to work, it doesn't.
I note the Boomerang utility is able to passthrough the authentication, with the command line:
vmware-vmrc.exe -h (servername) -M (vmid) -u (username) -P
And presumably that's going through an API as described here.
But that doesn't help me from a command line. Better still would be able to have a passthrough authentication like you can have for the VI Client.
