Please check if the IPA is running, the DS is running. Check the
logs that the compat plugin is loaded and working.<br>
You can also try looking at the compat tree from the server itself
to verify that the plugin, at least the DS part is functional.<br>
<br>
This generally smells as a firewall issue but I have not way to
prove or disprove the theory.<br>
