samba - Jul 2003 - Subject: WINS for a NAS (group names should not be multihomed)

we use a Samba 3.0.0beta2 as a PDC (node name 'TESTPDC', domain name
'MYDOMAIN') and WINS server
=-=-=-=-=-
# grep -i wins smb.conf
        wins support = yes
-=-=-=-=-
we also use a NetApp Filer F87 (netBIOS name 'JUPITER') configured
 - with only one nw interface, with an IP number shown here as ((NAS_IP))
 - to join a CIFS domain (no problem for now), and registered the Samba
   host as a WINS server

pertinent wins.dat snippet:
=-=-=-=-=-
"JUPITER#00" 1058250168 ((NAS_IP)) 64R
"JUPITER#03" 1058250168 ((NAS_IP)) 64R
"JUPITER#20" 1058250168 ((NAS_IP)) 64R

therefore it seems to work, but we cannot understand why log.nmbd contains:
=-=-=-=-=-
[2003/07/11 08:25:06, 0]
nmbd/nmbd_winsserver.c:wins_process_multihomed_name_registration_request(1140)
  wins_process_multihomed_name_registration_request: group name registration
request received for name MYDOMAIN<00> from IP ((NAS_IP)) on subnet
WINS_SERVER_SUBNET . Errror - group names should not be multihomed.

NAS consecutive loglines:
