Remove Old ADK from Users Key

Hi,

We have a user who is getting the "An ADK for a key was not found." message.

The user's key is referencing an old ADK, rather than the one it was replaced with quite some time ago.

Originally, only the old ADK was referenced on the user's key, but it now appears that both the old and new ADK are listed.

The user continues to get the warning when performing relevant actions, but can seemingly complete those actions.

Since the old ADK is no longer required, I told them to remove it from their key.

However, when selecting the old ADK in their key properties dialogue, the "Remove" action isn't high-lighted.

So how do "old" ADKs get removed from a users key?

Thanks, Neal.
