Security Assist with multiple logins/tables

I am working on a site which will use three different login screens/processes against three different database tables. However, when I try to secure a page, it only gives me the option of "grant access if...logged into employees," which is fine, as that is one of the valid tables, but the other two tables that I need validation for aren't listed, so I can't use them as a rule. What have I done wrong? Thanks!

The Security Assist wizard only allows you to select the One Table.

Why is it that you are using 3 separate user tables, for the site?

I'm hard pressed to think if a scenario where this would be needed.

In most cases only user table would be needed, you could use user level authentication to grant different access rights to different users.

There is a User Level Authentication tutorial in the Archived Documentation section of the security assist support page, it was written for SA1, but the concept is the same in SA2.

That's disappointing :( Each table collects different information and stores different information (they all have different purposes), so that's why I'm using three different tables.

you would need to run the security assist wizard 3 times, once to create the login / registration for the first table, again for the second and again for the third,

make sure that each time, you set the wizard to create the pages in unique location.
