samba - Aug 2005 - Preauthentication failed errors when trying to join Samba 3.0.14a to a W2k AD OU

Hi all,

I'm trying to add a samba 3.0.14a server (on Solaris 9 w/kerberos5 
v1.4.1 & OpenLDAP) to a Windows 2000 AD OU and I'm able to successfully 
run "/apps/krb5/bin/kinit username@NA.EXAMPLE.NET" but when I run ...
net ads join "PATH\TO\THE\RIGHT\SUB\OU"      I keep getting the 
following error message:

libads/kerberos.c:get_service_ticket(337)  
get_service_ticket  HOSTNAME$@NA.EXAMPLE.NET@NA.EXAMPLE.NET failed: 
Preauthentication failed

Here is an example of what I have in my smb.conf file.
        security = ads
        realm =  na.example.net
        encrypt passwords = yes
        use kerberos keytab = yes
        netbios name = havok
        workgroup = naex
        password server = dc.server1.ip.addr  dc.server2.ip.addr
       wins server = <ip addr>

I have an unmodified krb5.conf file, klist reports the following.

Ticket cache: FILE:/tmp/krb5cc_0
Default principal: username@NA.EXAMPLE.NET

Any suggestions?
