CmdGetAuthInfo calls run_cmd() with a list instead of a *-expanded list of arguments. Fix this to match the current run_cmd() prototype.
And think again if the current prototype conforms to the priciple of least surprise: Most exec- / run- / whatever- functions do expect ether a string to be run by the shell, or an argv list.
