so, if a user *must* exist in /etc/passwd, how did I end up with this in 
ldap after running 'smbpasswd -a ldap10':

dn: uid=ldap10,ou=users,dc=example,dc=com
uid: ldap10
sambaSID: S-1-5-21-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-1012
objectClass: sambaSamAccount
objectClass: account
objectClass: posixAccount
cn: ldap10
uidNumber: 10008
gidNumber: 10000
homeDirectory: /home/ldap10
loginShell: /bin/bash
sambaNTPassword: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
sambaPasswordHistory: 
00000000000000000000000000000000000000000000000000000000
  00000000
sambaPwdLastSet: 1457275169
sambaAcctFlags: [U          ]

and 'cat /etc/passwd | grep ldap10' returns nothing ??????

Rowland I have not written the smbpasswd man page!

If the man page says the user must exist. OK, then i believe it is true. 
If the man page says this tool works against the local smbpasswd store 
then i believe it is true.
If the man page says the local passwd store is the file 
/etc/samba/smbpasswd then I believe it is true.

*And* if if read this document
https://wiki.samba.org/index.php/Samba_3.4_Features_added/changed
section *Configuration changes* i am pretty sure this thread waste a lot 
of time.

Volkers fix (for me) just gets the password added, without the fix, the 
user is created but the password doesn't get added.

Well, lets put it this way, when and if the secondary segfault gets 
fixed, I will be proposing patches to the smb.conf manpage.

There is a page here: https://wiki.samba.org/index.php/Ldapsam_Editposix

This describes how to set up ldapsam without smbldap-tools

There is also this page (in japanese): 
http://wiki.samba.gr.jp/mediawiki/index.php?title=How_to_build_Samba_PDC_%28squeeze%29

They are both slightly wrong if used with Samba 4, syntax etc, but I 
have an NT4-style PDC running in a test VM, without any sign of 
smbldap-tools. The only problem seems to be in actually creating users 
and this is mostly fixed.
