Well then the docs on it are really stuffed and ambiguous ... but I
would be happy to know that this works ...
"This module authenticates a local smbpasswd user database. If you require
support for authenticating against a remote SMB server, or if you're
concerned about the presence of suid root binaries on your system, it is
recommended that you use one of the other two following modules"
I have already determined from Andrew Bartlett that there is ambiguity
in 'smbpasswd user database', as it should be 'samba passdb backend', to
be more clear that LDAP etc is supported in 2.2.7a on the DC.
But it may be out of date:
"25 Mar 2001"
Or maybe works better on samba3 ...

You can check:
$ strings /lib/security/pam_ldap.so |grep -i ntpassword
[bgmilne at bgmilne wxgps]$ strings /lib/security/pam_ldap.so |grep -i \
