OT: sudo question

[Mike Wright]

Hi Masters,

I would like to execute a command using sudo and not have to provide a 
password.  After much manpage time I added this:

mike    ALL=(ALL) NOPASSWD: /usr/bin/lxc

In theory this allows mike, from any and all hosts, to execute <lxc> 
without a password.

Nonetheless, "mike" executing "lxc" gets passworded, so there must be an 
error in my rule.

Any helpers?

TIA,
Mike Wright
