Determining User Role via DMO

I am trying to find a way to check if a user belongs to a program
specific role. Previously we had been using:
// Not Exact but I think it can be followed
hr = m_pDmoSrvr->GetTrueLogin(&login);
LPSQLDMOUSER pUser = 0;
hr = m_pDmoDb->GetUserByName(login, &pUser);
hr = pUser->IsMember(exclRole, &b);
But this does not seem to work if the user is a member of an NT Group
that has been added to the exclRole Role. I may not know what Group was
used to assign the Role.
Is there a way to determine whether the connecting user belongs to a
Role? I tried getting a LPSQLDMOLOGIN and using that but it did not
seem to work.
I'd be grateful for any pointers.
OtisIt looks like your checking to see of a login name, or windows username is a
member of a database role. Logins are not members of database roles; databas
e
users are. You want to test to see if the user that their login maps to is a
member of a database role, not if their login is a member of the role.

I believe you are correct but I have not been able to trace through the
options of the SQL-DMO objects to figure out how to manage it.
It seemed like the code I posted was getting the user object. But, at that
level, it seems to only check if the object itself is a member. It does not
check that the object(user) is a member of a group that are all members of
a role. That is what I have to figure out how to do.
