ok, here's the setup.

reseller.com (whm installed here)
login/pass: reseller/reseller

create client.com
login/pass: client/client.

now, you can log into the client.com using login/pass: client/reseller


Was this implemented to allow for trouble shooting issues?

Yes, its a good thing, so you dont have to keep asking your customers for their password, or resetting it :)

ok. Just making sure then.

Interesting to know. I have an account w/ a host that continually asks for my password for cpanel....

Thanks
