I'm not understanding. You will need to sketch this out:
1) Connection parameters for log in with <user_name>.
2) On log in the output from: select session_user, current_user;
3) Define '...set as owner of database automatically'.
Toomas,
things work for me as expected.
I guess as asked, you may want to show an example for your below statement to help understand better.
"The issue was that when a user logged into the database his session_user user was set as the owner of the database automatically."
