[Samba] security=domain problem: "could not fetch trust account password for domain"

When configuring a SunOS 5.9 box running Samba 2.2.8a with security=domain,
as per
http://us2.samba.org/samba/docs/using_samba/ch04.html#samba2-CHP-4-SECT-7 I
get the following error "could not fetch trust account password for domain"
when trying to connect to a share via 'net use * \\server\share

However, 'security=user' works correctly.  'security=domain' will fall back
onto the user's smbpasswd successfully.  I'm configuring the box to be a
domain member, not a PDC.  We do not have WINS setup on the box.

A sample error log entry is:
[2003/10/23 12:22:07, 0] smbd/password.c:domain_client_validate(1558)
  domain_client_validate: could not fetch trust account password for domain

smb.conf is:
