Hi I have a small problem with joining a XP box to a Samba domain, which I hope that someone can put some light on. The setup: Samba 3.0.4 using ldap for users. All users are created with both posix and samba accounts. Users can login with ssh (pam/nss), smbclient and net use \\pdc\share /USER:username (also from XP pro). W2k workstations can join the domain. When I try to join a XP (pro) workstation I get the following in the log: [2004/06/01 11:51:47, 2] lib/smbldap.c:smbldap_search_domain_info(1344) Searching for:[(&(objectClass=sambaDomain)(sambaDomainName=SAMBA))] [2004/06/01 11:51:47, 2] lib/smbldap.c:smbldap_open_connection(639) smbldap_open_connection: connection opened [2004/06/01 11:51:47, 2] smbd/sesssetup.c:setup_new_vc_session(602) setup_new_vc_session: New VC == 0, if NT4.x compatible we would close all old resources.

I have tried both with and without the signorseal registry change. The most recent info seems to indicate that it is not needed, but I was not sure. The machine account gets created automatically. I have tried to create it manually (using smbldap-useradd -w from IDEALIX's smbldap tools), but with the same result. The global section of the smb.conf file are included below. I have searched the archives and google but found nothing except one other having the same problem, but no solution was found. Does anyone have any ideas? Best regards Mikael M.
