OK, that confirms it, in the last smb.conf you posted for the DC, there
are these lines:

        realm = DOMAIN.BR
        workgroup = DOMAIN.BR

You have just posted that your workgroup name is 'domain.br' now
leaving aside that having '.' in a workgroup name doesn't seem to be a
good idea, your workgroup and realm in smb.conf are the same, yet the
alterations you made to the command I posted are
This means your dns name is 'campus.domain.br' and as your realm is
supposed to be the uppercase dns name, the line in smb.conf should be:

       realm = CAMPUS.DOMAIN.BR

Yet you also posted that you used '--realm=domain.br' during the
classicupgrade, so I am getting really confused now ;-)
