[one-users] about NIS

[Ruben S. Montero]

Hi Esperanza,

Running OpenNebula does not really need NIS. You can just create a
oneadmin account in all the cluster nodes with the SAME UID and GID.
Some cluster management tools use this approach instead of
using/configuring NIS. In the case of OpenNebula, as we do just need
one account you can just ignore NIS.

Cheers

Ruben
