[Samba] Getting samba ldap to work?

[Tim Tyler]

   Samba experts,
    I am having problems getting samba 3.0.8 working with ldap 
authentication on an aix 5.1 system.   I have successfully gotten ldap to 
work with telnet, ftp, ssh, finger, etc.   But, I seem to be really stuck 
on getting samba to work for some reason.   I am running my ldap server on 
another host (Debian).  I did enter in a samba schema into the slapd.conf 
file.   I have both opendlap and nss_ldap installed on the aix server, 
though I am not sure if samba even tries to use them or not.
  Questions:
1. Does samba use openldap or nss_ldap?
2. Should I consider using pam support?  If so, do I need to recompile 
samba for pam support?
3. I notice that some people configure their smb.conf file to use ldap 
server or passdb backend =.  Which should I be using?
#      passdb backend = ldapsam:"ldap://lincon.beloit.edu"

         ldap suffix        = "ou=People,dc=lincon,dc=beloit,dc=edu"
         ldap admin dn      = "cn=admin,dc=lincon,dc=beloit,dc=edu"
#       ldap port          = 389
         ldap server        = 144.89.254.9
         ldap ssl           = no
         ldap machine suffix = ou=Machine
         ldap user suffix = ou=People
         ldap group suffix = ou=Group

NOTE: When I use passdb backend, I never get a prompt to login with my 
username and password.  It simply fails stating their is no backend.

  When I comment out that and use the ldap server line (with ldap port 
commented out), I get a prompt, but get these errors in the logs:
2005/01/18 15:20:11, 1] lib/util_sock.c:get_peer_name(959)
   Gethostbyaddr failed for 144.89.40.114

   Gethostbyaddr failed for 144.89.40.114

I feel like its not really getting to the point of inquiring for a 
username, etc.  Any suggestions are much appreciated! -thanks
