This means that your clients and MDS do not have their password and
group databases in sync.  Synchronize them (either with sneakernet or a
centralized database like NIS or LDAP) and this should go away.

Of course, you need to keep them in sync, so changes to a sneakernet
maintained database need to be propagated -- which is why NIS or LDAP
become useful if changes are more than infrequent.
