[one-users] Using images accessible to the nodes but not to the server?

[Carlos Martín Sánchez]

Hi,

You may be getting the "unable to set user and group" error message because
oneadmin user and group IDs are not the same in the front-end and the hosts;
but there are different causes. Take a look at the archives [1], you may
find some hints.

Regards.
