Problems with LDAP ldapsam and Older Versions of smbldap-tools
If you use the smbldap-useradd script to create a trust account to set up
interdomain trusts, the process of setting up the trust will fail. The
account that was created in the LDAP database will have an account flags
field that has [W ], when it must have [I ] for interdomain trusts to work.
Here is a simple solution. Create a machine account as follows:
root# smbldap-useradd -w domain_name
Then set the desired trust account password as shown here:
root# smbldap-passwd domain_name\$
Using a text editor, create the following file:
dn: uid=domain_name$,ou=People,dc={your-domain},dc={your-top-level-domain}
changetype: modify
sambaAcctFlags: [I ]
Then apply the text file to the LDAP database as follows:
root# ldapmodify -x -h localhost \
-D "cn=Manager,dc={your-domain},dc={your-top-level-domain}" \
-W -f /path-to/foobar
Create a single-sided trust under the NT4 Domain User Manager, then execute:
root# net rpc trustdom establish domain_name <----- important
It works with Samba-3 and NT4 domains, and also with Samba-3 and Windows
200x ADS in mixed mode. Both domain controllers, Samba and NT must have the
same WINS server; otherwise, the trust will never work. <---important

(Added info)
I would try disabling the machine account scripts, and manually creating
the unix level account domain trust with what ever tools you use to for
ldap accounts. That should help eliminate if the script is just not
running correctly.
When you join local windows machine to the domain, are they adding
correctly? Is the underlying unix account for the machine created?
You could also probably run the script from the command line
/var/lib/samba/sbin/smbldap-useradd.pl -w thedomainname
