Orphan domain. cannot remove

[jorfermo]

Hi there.

I'm trying to remove a domain that seems to be orphan. When I exec:

domain -r <mydomain>

I get that (translated):

It's been an error during domain deletion. Domain <mydomain> doesn't depends on any client.

If I look for <mydomain> domain in control panel I don't find anything but it's there because if I try to create it again a message appears saying domain already exists.

¿Any idea of how can I delete this domain definitively?

Thanks in advance!!!
