Single-on installation

Question

I need some help configuring the Single On installation. I've set up a q2a site and now I want to create a network. So I followed the instruction in http://www.question2answer.org/single-sign-on.php but I cant understand this part:

1. In the qa-external-users.php file in the qa-external folder, modify the qa_get_mysql_user_column_type() function to return the appropriate MySQL column type for your user identifiers. For example, if you use textual identifiers, return VARCHAR(x), where x is the maximum length. If you use numerical identifiers, return the appropriate numeric type, such as INT UNSIGNED or BIGINT. Ensure you get this right because it will be used in many of Question2Answer's MySQL tables.

What is the appropriate return to use if my db was created by question2answers? Where do I get that answer?

 

Thanks a lot

Answer 1

After looking into the database created by question2answer I realized the type was 'INT UNSIGNED'.
