Just to get these things out of the way

  CentOS (2.6.9-42.0.10.ELsmp)

  # yum list installed | grep openssl
  openssl.i686                             0.9.7a-43.14           installed
  openssl-devel.i586                       0.9.7a-43.14           installed

  # yum list installed | grep samba
  samba.i386                               3.0.10-1.4E.11         installed
  samba-client.i386                        3.0.10-1.4E.11         installed
  samba-common.i386                        3.0.10-1.4E.11         installed
  samba-swat.i386                          3.0.10-1.4E.11         installed

  # yum list installed | grep samba
  nss_ldap.i386                            226-17                 installed
  openldap.i386                            2.2.13-6.4E            installed

  openldap-devel.i386                      2.2.13-6.4E            installed
  openldap-servers.i386                    2.2.13-6.4E            installed
  smbldap-tools-0.9.2

  I think that should cover most of what someone else would need to know.
The goal is to have a PDC that uses Samba and LDAP.  I have used guides
like the guide from here
http://www.idealx.com/content/view/184/169/lang,en/ .  I seem to have
LDAP and Samba working and the smbldap-tools working properly.  I can
use the LDAP Account Manager ( http://lam.sourceforge.net/ ) to add
users to the domain and then use ssh and pam_ldap to connect with those
user names.  I can add users to the domain, and use the domain usernames
and passwords to connect to shares off the server.  I can also add
machines to the domain from Windows without any problems and they show
up in LDAP.  The part that has me stumped is that I can't  seem to login
to the domain from one of the domain accounts.  I can login with the
local admin account then use a domain login to login to domain shares I
just can't do the initial Windows login.  Turning the samba debugging up
to 3 doesn't seem to help since I see log messages like
  "  check_ntlm_password:  authentication for user [testuser] ->
[testuser] -> [testuser] succeeded"
  which would make me think that things are working properly.  I kinda
suspect that the problem could be with smbldap-tools somewhere since I
was able to switch samba to authing from the /etc/samba/smbpasswd file
and it was able to login fine though I have yet to figure out which
script is called on Windows logins.  Any help would be appreciated.

smb.conf (I replaced the server address with 'server.address' but that's
the only change I made for posting to this list.
