Answers to Common Problems

This sections introduces workaround instructions for some problem situations.

Troubleshooting GSSAPI Authentication

When connecting from a Windows 5.x or 6.x client to a Windows 4.x server using GSSAPI authentication, if authentication fails although GSSAPI has been correctly configured, you may have to disable the LMHOSTS lookup on the client-side computer. Follow these instructions:

  1. Select Control Panel → Network Connections.

  2. In Local Area Connection, right-click and select Properties.

  3. In the Local Area Connection Properties dialog box, General tab, select Internet Protocol (TCP/IP) and click the Properties button.

  4. In the Internet Protocol (TCP/IP) Properties dialog box, in the General tab, click the Advanced button.

  5. In the Advanced TCP/IP Settings dialog box, in the WINS tab, clear the Enable LMHOSTS lookup check box.

  6. Restart the client-side computer.

Password Window Loses Focus

In some cases on Windows clients, the window for the password or the public-key passphrase can lose focus. This means that the password window is shown active on the screen, but when you start typing your password, the asterisks do not appear in the box. If the actual focus happens to be in an other window, your password or passphase may appear there.

The password window loses focus most often when you have the Tectia Connection Broker status window open. So the first workaround is to make sure the status window is not open while you start logging in.

A permanent solution to the problem is to modify the Windows settings that control the behaviour of the applications. By default, Windows has on a setting that prevents applications from stealing the focus. As a workaround, you can allow applications to steal the focus. Note that the setting affects all Windows applications, not just the Tectia Connection Broker.

To be able to change the setting, you need to download the Microsoft Tweak UI utility program. Follow these instructions:

  1. Download the Microsoft Tweak UI utility from: http://windows.microsoft.com/en-US/windows/xp-downloads.

  2. Install the Tweak UI on your computer with the help of the installation wizard included.

  3. Start the program from the Start menu.

  4. Go to the General - Focus view and clear the Prevent applications from stealing focus check box as shown in the following figure.
