[one-users] Err in opennebula java example program "Trying to allocate the virtual machine... failed! [VirtualMachineAllocate] User couldn't be authenticated, aborting call. "

[Hector]

I'm not familiar with java, but for the authentication problem try calling  
new Client with a user:password tuple:

Client(java.lang.String secret, java.lang.String endpoint)

http://opennebula.org/doc/3.6/oca/java/org/opennebula/client/Client.html#Client(java.lang.String,  
java.lang.String)
