[jcifs] Member in Domain?

[eglass1 at attbi.com]

If you have obtained a non-null NtlmPasswordAuthentication object from the 
doAuthentication call (i.e., the client has responded with a well-formed type-3 
message), and you want to check if the response will successfully authenticate 
them against a specific domain, you should be able to do:

public boolean isInDomain(NtlmPasswordAuthentication np,
        UniAddress domainController, String domain) throws IOException {
    try {
        if (!domain.equalsIgnoreCase(np.getDomain())) return false;
        SmbSession.logon(domainController, np);
        return true;
    } catch (SmbAuthException ex) {
        return false;
    }
}

The domainController above should be the same box which produced the type-2 
challenge, i.e. via SmbSession.getChallenge(domainController)
