samba - Jan 2008 - Joining an ADS domain - issue with the netlogon pipe (anonymous access required)

I have a problem joining Samba to a Windows 2003 sp1 ADS domain. I'm 
running Samba 3.0.28 on Solaris 10 with MIT Kerberos 1.6.3 and OpenLDAP 
2.3.38.

When I run 'net ads join' i get the following error.

./net ads join -S domaincontroller.mynet.mydomain.com -U Administrator 
-d10

  return code = -1

A temporary work around for this is to add "netlogon" to the group
policy
under "named pipes that can be accessed anonymously" on the PDC. Once
the
Windows SA's changed this the 'net ads join' worked fine.

The Windows SA's will not open this on the production domain.

Is there a way to get Samba to join an ADS domain correctly without having 
to enable anonymous access to the netlogon pipe?

Thanks,

Paddy
