working with roles where there is multiple applications in the same datasource

We have several applications that uses has the same users and for authentication they are stored in the same database with different application names.   Is there a way to get add a user but be able to add that user to any role in any of the roles for each application.   I have never used .net authentication before and this is all new for me.   THese applications were existing previous and I was asked to make find a way to manage user from one location.

can you clarify what you are looking for?

<manage user from one location
Create admin application that will point to table where user vs permissions setup
and make validation of the user permissions based on info in the table that you may adjust:

user           application     role            permissions
krbnldy,        IE                admin             0                                  
EZ                 IE                user               1

this is what I am trying to achieve
applicationName      userroles                            Users
\ABC                          admin,  Edit, ViewOnly      Can be just a few or many users
\DEC                          admin  (here the admin is seperate from the application above and may or may not be the same users

There are several applications and each application has can have the same users with different permission levels.

I want to manage all this fom one database as the users are all stored there.
