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):
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.
