I have just started an old vm with samba 3.6.6 as pdc and openlap as 
backend. smbpasswd -a someuser does not work, if someuser does not 

if I create a posix user with useradd in /etc/passwd and then try to add 
this user with smbpasswd -a to openlap i get the same error.

so my 2 cents on this thread:
passwd -a someuser 
has never worked with a ldap backend.

And as Volker said:
"and I am out of the openldap config business long enough that I don't 
get this set up quickly."

I believe he has just forgotten how smbpasswd works. So currently Volker 
is trying to fix something which do not need any fix. In fact he adds 
new functionality to smbpasswd. But does this makes really any sense?
