vmware vdiskmanager User not authorized for host agent contact.

Hi guys,

I've been trying for a couple o' days now to export a vmdk from ESXi to my local machine using vmware vdiskmanager and the command as follows:

vmware-vdiskmanager -S -h 192.168.1.9 -u myuser -f "E:\password.txt" -t 0 -r "[datastore1] TestVm/TestVm.vmdk" "E:\vm.vmdk"

myuser belongs to the Administrator group but whenever I run that command I get the following:

[NFC ERROR] NfcNewAuthdConnectionEx: Failed to connect to peer. Error: 550 User not authorized for host agent contact

VixDiskLib: NFC Error during user connect: 550 User not authorized for host agent contactFailed to convert disk: Cannot connect to the host (0x4650).

If I issue the same command with the root user, it works just fine, but I need it to work with an Administrator account.

I couldn't find anything on why it shouldn't work with an administrator account, given that the root account belongs to the same group.

Any thoughts would be kindly appreciated.

Thanks!
