I think 1:1 relation is sufficient. No special need for 2 sso accounts
for the same local user.
Relation can be contained in new property of XWikiUsers class. ("ssourl"
string property for example. or dblist property in case of 1:n relation)

Yes. This is one of major advantages of sso. Isn't it?
This is very useful for users which want simply add some comment and
don't want to full register.

I think that provide new xwiki sso account for already sso users is
useless :)
We should not provide xwiki sso accounts for sso users without password
in their xwiki user profile.
