Dont do that!  Samba is broken unless it checks an accounts validity
before allowing a user to access it.  If we are using winbind, my
understanding is that we are providing the PAM modules anyway - in which
case the winbind pam module should handle this as for all other

The only vaid case for not checking our local pam setup is for a BDC
type setup, where all authentcations are referred to another server, and
no access is granted to any local resources.  This is not true for real
BDC's however, as they still use a local smbpasswd for when the PDC
fails.  So theres not currently a case for this.  And if there is,
pam_permit.so is designed for exactly this situation, and can be
configured by the system administrator if desired.
