multiple smb domains at once?

[Les Mikesell]

Is it possible to configure PAM to check passwords via SMB against
more than one windows domain?   The users in question have
local accounts on the Linux box but the passwords are currently
being check against a single windows domain.  Now the windows
admins are moving people to a different domain and for the
transition, I'd like to let people log in if their login
and  password matches in either domain.  Authconfig sets up
one. How would I add another?
