The LDAP server is unavailable.

We have been using your component in SQL2008. Works fine. It's awesome.
Now we have SQL2012 and I cannot get the component to work. Every time I try to drag it into the DataFlow, it presents the error below.

It is driving me nuts! What am I missing?
Thanks in advance.

TITLE: Microsoft Visual Studio

The component could not be added to the Data Flow task.

Could not initialize the component. There is a potential problem in the ProvideComponentProperties method.

Judging by the error message, it appears that you are using the SQL2008R2 component on the SQL2012 box. The way I came to this conclusion is by seeing the references to ITDSComponentMetaData100, on SQL2012 it should be 110.
I would uninstall the component and download the latest version. When downloading, make sure to grab the SQL2012 version of the component.
I hope this helps, let me know if you have any additional questions.
