[Samba] samba+winbindd problem joining Ubuntu 20+ to windows 2000 domain
Hi, people. How are you?. I hope you are very well
Could you help us, please?. We've a problem with Ubuntu+samba+winbindd
joining an old Windows 2000 Active Directory domain (we are testing
migrate our domain to SAMBA4 but, for now, we must continue using the
current domain).
We have no problems joining Ubuntu 18 and, in the past, we've joined
Ubuntu 20 PCs. It seems to be some update in libraries or packages
involved in interactions winbindd/samba-Windows 2000 AD has broken
something in our environment and now, join an updated Ubuntu 20 can't be
done. We can install ubuntu 18, join the PC to domain and then, update
to Ubuntu 20 but is a pain because we are planning go to ubuntu 22.
*In the PC (ubuntu 20) we are trying to join:*
a) Result of net ads:
sudo net ads join -U Administrador
[sudo] contrase?a para sistemas:
Password for [OUR\Administrador]:
ads_print_error: AD LDAP ERROR: 53 (Server is unwilling to perform):
00002077: SvcErr: DSID-031D0AAB, problem 5003 (WILL_NOT_PERFORM), data 0
connect_to_domain_password_server: unable to open the domain client
session to machine mailsrv.OUR.REALM. Flags[0x00000000] Error was :
NT_STATUS_ACCESS_DENIED.
Failed to join domain: failed to verify domain membership after joining:
{Access Denied} A process has requested access to an object but has not
been granted those access rights.
c) After that, winbindd can't be started. In winbind logs:

*Additional Info; may be important:*
* We noted the event 5772 is also logged intermitently for other
PCs already joined to the domain, all of them with Ubuntu 20. We
think this log happens when the pc tries to change its password.
Those PCs are running ok in domain but may be this event is the
tip of an iceberg.
* May be event 5722 is logged also when joining Ubutnu 20 to
domain because PCs is trying to establish its password in that
moment?.
Thanks in advance.
