Move from unicodePwd to userPassword?

I just wanted to bring this up on the list:

I intend to move us away from using attribute names that match AD where
we do not know the format.  In particular, for unicodePwd, I want to
move to userPassword.  I am also interested in moving and changing the
password history attribute and format.  Samba3 using a salted history,
and I think this is a valuable security improvement.  (We get a glimpse
at this format in SamSync.  I need to double-check the implications of a
change here).

This would make it easier to implement the unicodePwd set operation,
because it would not conflict with our internal use.  I also take Luke
Howard's hint seriously:  If we later migrate to match Micorsoft,
changing formats but not names sounds very painful.

If we did this the LDAP password set could then be handled by a normal
LDB plugin, which would call out to the samr_password.c code.  (This
would then call back into ldb to set the password, on the userPassword

These are fairly easy 'internal' changes as none of these attributes are
externally visible over LDAP.
