Thanks for that Steve.
I've now installed the newer ldap packages like so:

	ii  ldap-utils                  2.4.10-2                    OpenLDAP utilities
	ii  libldap-2.4-2               2.4.10-2                    OpenLDAP libraries

I've also added the following to the /etc/samba/smb.conf file and restarted samba. Does it look right?

	log level = winbind:4

However I don't think I thought to check the log.winbind before...
So here is what I've found with the default log level (which I guess is 0?)

	winbindd: error.c:272: ldap_parse_result: Assertion `r != ((void *)0)' failed.
