My bad. This has nothing to do with clients. I just need to specify  
the domain.
I found the answer with a log level = 3 on the homes server.

On a client with the smb.conf workgroup parameter unset,
smbclient //new-server/user -U user
is rejected and the server's log shows:
[2011/02/17 15:17:23,  3] libsmb/ntlmssp.c:745(ntlmssp_server_auth)
  Got user=[user] domain=[WORKGROUP] workstation=[CLIENT1] len1=24  

On a client with the workgroup set to MYGROUP (which is the case on  
some packaged
distributions of samba), smbclient is also rejected and as one could  
expect we have:
[2011/02/17 15:09:13,  3] libsmb/ntlmssp.c:745(ntlmssp_server_auth)
  Got user=[user] domain=[MYGROUP] workstation=[CLIENT2] len1=24 len2=24

On every client, specifying the domain to which the file server is  
joined works:
smbclient //new-server/user -U user -W MYDOMAIN

AFAICS it was not required to specify the domain with 3.0.x member  

Sorry for the noise.
