samba - Aug 2005 - Help with ADS authentication from Windoze

Here is my situation:

I have an AIX 4.3.3 machine, that I have compiled open-ldap, kerberos5 
(1.3..6), and Samba 3.0.20. 

Here is my smb.conf file:

[global]

realm = REGION.DOMAIN.COM
security = ADS
password server =  randomdc.region.domain.com
workgroup = REGION
client use spnego = yes
;winbind separator = \


[homes]
   comment = Home Directories
   read only = no
   create mode = 0750
   browseable = no

[styx]
   comment = Styx
   path = /styx
   public = yes

[styx1]
  comment = Styx1
  path = /styx1
  public = yes


Here is my krb5.conf 

[libdefaults]
        default_realm = REGION.DOMAIN.COM
        default_tkt_enctypes = des-cbc-md5 ; or des-cbc-crc
        default_tgs_enctypes = des-cbc-md5 ; or des-cbc-crc
[realms]
        REGION.DOMAIN.COM = {
        kdc = randomdc.REGION.DOMAIN.COM
        }


I was able to add this machine to the active directory (by the way, we are 
running 2003 ADS). 

I am also able to get info from wbinfo -u and wbinfo -g.

Here is where it becomes a problem:

I cannot authenticate from my Windoze box to this AIX machine running 
Samba.

Here is the error message in log.smbd:

[2005/08/30 07:46:05, 1] smbd/sesssetup.c:reply_spnego_kerberos(263)

However, I also see this in the log too:

Here is some interesting stuff in log.nmbd (probably not related):


[2005/08/30 07:47:43, 0] nmbd/nmbd_namequery.c:query_name_response(101)

Here is winbindd log file:

Any suggestions ? Any one else come across this ?

Thank you.
