I would try installing it first in the default settings, and see how it feels.
In owncloud you can use single sign on.
I think until Monday the 10.0.3 Appliance will be ready for download, so I would try it, because 10.0.3 is better than the 10.0.1, what you currently have.
Hey dmitry I redeployed the image with default settings and installed owncloud. Just wondering but the single signon you are referring to is setup thru user authentication in owncloud? I need to add the ldap server for my domain in here for single signon to work or is it setup somewhere else? Thanks
