Hi Rowland,

ldap doesn't work for me either:

That being said, I think I know why that doesn't work.  It's because on 
the server, I haven't changed the default "ldap server require strong 
auth = Yes" to "No".  That's because my team was very opposed to this 
option due to the security implications.  We have other services 
authenticating via ldaps.   Unfortunately, smb.conf won't let me enable 
"ldap server require strong auth" from only a certain IP.

So without the ability to use ldaps, I guess I can't use samba-tool from 
another host.  This is unfortunate. :(   Should I be submitting a bug 
report about ldaps not working?

Jason.
