samba - Jan 2004 - No Mapping between account names and security IDs was done

I had inquired about this in that past and was not given a direct
answer. For whatever it is worth, here are my findings, also in response
to this thread

I just discovered that you should make sure that samba has not generated
a new sambaDomainName=<domainname> entry in LDAP that contains a SID
that's different than the one used in your machine and user accounts.
