Actually, there is no way to obtain such information.
PAM (openpam at least) calls each module in clean enviropment,
so it doesn't know anything about other modules.

You can, however, explicitly call pam_winbind.so from you module
providing some kind of pam emulation to see it's return value.
But in that case you'll break original call flaw.
