[Samba] Samba 3.x server with LDAP backend doesn't work

Did you try w/o start TLS support?   I realize this can have security 
implications, so this is only to see if the problem is with TLS or with 
the configuration in general.

It the LDAP server is on the same server as the samba server then I 
don't think you will need TLS encryption, since there isn't LAN traffic 
to snoop.

don't forget to set set the ldap password with "smbpasswd -w"

Also I think "ldaps" means ldap over SSL, not ldap+tls.   I would also 
use ldapclient tools (e.g. the command line ldapsearch or the gui Apache 
Directory Studio ldap browser and editor) to make sure you can connect 
to the ldap server via LDAP, LDAP+TLS and/or LDAPS-over-SSL.     You 
need to make sure you have all the certificates configured correctly.
