SSO multiple domain on 1 joomla instance

I have multiple domains running on 1 joomla instance....

exampe
domain.nl for dutch version of the joomla intance
domain.com for english version of the joomla intance
domain.de for german version of the joomla intance
ect

all redirects to 1 joomla installation with is multilanguage.
when a user login its all ok but when opening a course the user the user redirects to the default domain and has he to login again.

Is there a way to solve this so sso will work as well?

im using joomla 3.3.3 and moodle 2.7.1 and Joomdle 0.95

I am sorry, but at this point, I can't think of a way to make that work withouh modifications.

I guess you could save joomla host info somehow for the user, and then use that info on login/redirects, but that would need a quite big modification in how Joomdle work. That is, if it is even possible, as I have not really though about any problems that may appear.

hmm pitty..... but is there posibility to install fi the joomlde aut plugin in moodle a option?

Sorry, I did not understand that.
