I am just getting to grips with turnkey and proxmox so if this is my noobness I apologise.
The root password and the password chosen which actually was password only works with webmin.
I had a bit of a look around and from the owncloud conf file I got the owncloud user and dbpassword
So I could log in as owncloud.
I still don't know the owncloud admin password and its not a straight hash its some salt or combination of something. So that stopped me there.
I have tried resetting the password in webmin and it says it does it.
At a guess mysql is running with no password like a default install and credentials for the owncloud db.
what the admin password is for owncloud I don't know.
PS have you guys any plans for samba4?
