[Samba] Problems with ADS join after Samba update on FC4

Hi,
I used to have a working Samba + Winbind configuration in ADS mode under FC4;
Samba version was 3.0.14a-2. I joined a W2k domain, and winbind correctly
returned the user information. krb5.conf and smb.cong have been modified
according to Howtos and tutorials found on the net.
One day Samba has been updated to 3.0.23a-1.fc4.1 and it stopped working.
No modification has been done to the configuration files, but it cannot join the
domain any more. Kerberos still works (kinit works as expected and klist shows
the ticket).
After a lot of time spent trying to understand the problem I uninstalled the new
Samba version and reinstalled the old one without modifying anything else,
and it started working again. Then I ran "net ads info" and "net ads join" with
debugging enabled and saved the results. Then I reinstalled the updated version
and, with no surprise, it did not work any more. Then I ran the same commands
with debugging enabled and saved the results. I tried also on a different machine
with FC5 and the same (new) version, and it fails exactly the same way.
By comparing the output of the two version I can see some differences; it looks
like the join command fails the connection to the ADS server, while the info
command is unable to get the server time information; can these two things
be related somehow? Consider that in this installation both the domain name
and the realm of the ADS server are a single word, with no dots.
The output of the four tests is somewhat long (1300 lines total); if someone can
help me I will send it by private email. I will try here to cut and paste some
relevant part (removing the parts with no differences).
Thank you for any help
Elio
