samba - Mar 2008 - winbind 3.0.28a not working with nt4 -> windows 2003 trust domain

Hi Folks,

I have upgraded from samba 3.0.28 to 3.0.28a
and now users aren't able to connect to the
samba share. Winbind is logging this message:

[2008/03/25 15:07:12, 5]
passdb/secrets.c:get_trust_pw_clear(720)
   get_trust_pw_clear: could not fetch clear text trust account password
for domain DOMAIN

the samba box is joined in an old nt4 domain.
Then there is a trust to a windows 2003 domain
(where there are the user accounts).
My only option is switching to 3.0.28
