Login mappings won't be in the database itself. Logins are for the server and users are for the database. Login mappings indicate what databases the logins have access to. The login allows the connection to the server and then a login is mapped to a user in whichever databases.
In SSMS, go to Security -> Logins. All the people who need to have access should have their logins listed there. Right click on a login, select properties. On the left of the login properties page, click on user mappings.
