User listing with combination of roles assigned to them

Hi,

I need to list all the users in our system with a combination of roles assigned to them.

Example:

User1 = Role1 + Role2 + Role8

User2 = Role1+ Role3 + Role8

User3 = Role1 + Role4 + Role8

I want to extract a listing of users with Role1 and Role8 assigned to them.

How do I go about doing this??
