Samba 3.0 with Active Directory net ads join problem

[Jonas Back_2]

We have a AD-domain using Windows 2003 servers. We want to join our RH ES3 Samba (3.0.0-14.3E that was shipped with ES3) to our AD-domain. We get no error when running kinit but when trying to join the domain with "net ads join -U username" we don't get any successful nor errormessage. If you look at the log at the DC we get the following:
-----CUT-----
Pre-authentication failed:
User Name: username
User ID: PPM\username
Service Name: krbtgt/DOMAIN.COM
Pre-Authentication Type: 0x0
Failure Code: 0x19
Client Address: 192.168.xx.xx
-----CUT-----
The user we're using is a Domain Admin. We've followed most of the guides on the net and it should simply work with net ads join. We have also tried pre-creating a computer account in the AD domain for the server. In the configfiles below we also tried specifying a password server = in and workgroup = DOMAIN in smb.conf. There's no info in the krb5-logs.

Any ideas?


/etc/krb5.conf
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log

default_realm = DOMAIN.COM
dns_lookup_realm = false
dns_lookup_kdc = false
[realms]
DOMAIN.COM = {
kdc = dcserver1.domain.com:88
admin_server = kerberos.example.com:749
default_domain = domain.com
}

.domain.com = DOMAIN.COM
domain.com = DOMAIN.COM

[appdefaults]

}
