[Samba] net rap validate

[dariemp]

I'm trying to validate user/password pair in a domain without actually being joined (no account in AD server). It is important for me to do it whith this particular condition. My Samba version doesn't implement this command yet (net rap validate). Is there another way to do it? My Samba version is 3.0.33. Should I upgrade to a specific version in which this command is already implemented?

regards,
