pam login authorization using both local and winbind

I have a situation where I need the linux server to accept either local password or active directory password. Below is the relevant code from /etc/pam.d/system-auth.

auth required /lib/security/$ISA/ auth sufficient /lib/security/$ISA/ likeauth nullok #auth sufficient /lib/security/$ISA/ use_first_pass auth sufficient /lib/security/$ISA/ auth required /lib/security/$ISA/
