Password (DES vs Plugin)

[kdh4318]

Hello,

Currently, if the plug-in password is set, the plug-in password is used as authentication method rather than the DES password.
Is it possible to authenticate through the DES password even if the plug-in password is set?

I tested it by modifying the SetDSMPluginStuff() of ClientConnection.cpp in vncviewer.sln.

Code: Select all

if (!_stricmp(m_pDSMPlugin->GetPluginParams(), "VNCPasswordNeeded"))
{
    if (strlen(m_clearPasswd) == 0)
    {
        AuthDialog ad;
        if (ad.DoDialog(dtPass,m_host,m_port))
        {
            strncpy_s(m_clearPasswd, ad.m_passwd,254);
        }
    }
    strcpy_s(szParams, m_clearPasswd);
}
else
    strcpy_s(szParams, "NoPassword");

I tested this part after modifying it as below.

Code: Select all

if (strlen(m_clearPasswd) == 0)
{
    AuthDialog ad;
    if (ad.DoDialog(dtPass,m_host,m_port))
    {
        strncpy_s(m_clearPasswd, ad.m_passwd,254);
    }
}
strcpy_s(szParams, m_clearPasswd);

I confirmed that even if the plug-in password is set, the authentication proceeds to DES.
However, actually entering the DES password set in winvnc did not succeed in authentication.

Could you give me some advice?

Best Regards
