Please don't ever do that again, never send the verbose output from
testparm, just send the output of 'cat'

I believe your smb.conf on disk will look like this:

 [global]
        netbios name = ZION
        realm = SSCI.COM
        server string = Samba Server Version %v
        workgroup = SSCI
        domain master = No
        client ldap sasl wrapping = plain 
        ntlm auth = Yes
        private dir = /etc/samba/private
        security = ADS
        smb passwd file = /etc/samba/private/smbpasswd
        create krb5 conf = No
        winbind enum groups = Yes
        winbind enum users = Yes
        winbind nss info = rfc2307
        wins server = 192.x.x.x

Before going any further, can I ask how you how (once you have joined
the domain) you propose to make your Windows users known to the Unix
system ? There is a distinct lack of 'idmap config' lines.

Does the /etc/resolv.conf point to a DC as a nameserver ?
Does the proposed Unix domain member get its IP via DHCP ?
What is in /etc/hosts ?
What is in /etc/krb5.conf ?
