Hi to everyone.

In commercial products as EMS QuickDesk or IBAdmin there is a tool called Grant Manager, where one can set roles and assign users to that roles. I know I can get role names with something like this:

SELECT RDB$ROLE_NAME
FROM RDB$ROLES

How can I know if a User is assigned to a Role?. Is there a function like GetRolesOfUser(User: String): TStrings?

Thanks in advance.
