alternative password database, using ldap instead of , private/smbpasswd

[Luke Kenneth Casson Leighton]

hee hee, jean francois is going to be annoyed.  this code is still under
"definite alpha" status, but i really, really wanted to get it in there
asap.

so, the latest cvs checkin adds the ability to use an ldap schema for the
passwords, not that i know what one of those actually is (only kidding:
i've just never set one up yet).  here it is:

Subject: LDAP schema

objectclass sambaAccount
        requires
                ObjectClass,
                cn,
                objectSid
        allows
                accountExpires,
                adminCount,
                badPasswordTime,
                badPwdCount,

your host for this wonderful set of code is mr Jean-Francois Micouleau
<Jean-Francois.Micouleau at utc.fr>  please do not give him any hassle: i
have just landed him in it by checking his development code in :-) :-)

lots of love,
