I think 'migrate' option is not used a lot. On some distro, this 
option is set by default and makes troubles.

But on standalone boxes, pam_smbpass is still used to sync UNIX
password to Samba. This works fine so we do not need any change to
this module, I think.

Currently, there are no altinatives, so pam_smbpass is still
required.
