Is this normal or a bug?

Filr Version:

AD users have their home dir populated and Filr does see the Net Folder server.

Changed a users Home Dir setting in AD to a *NEW* file server that Filr does not yet know about.
Waited a half an hour.

Ran a manual Sync All.

Filr sees other user accounts added/deleted/modified, but not the one I changed.
New NetFolder server does NOT show up.

The only way I could get Filr to see the change was to delete the user out of Filr and re-run the sync, so that it added the user and then the New NetFolder shows up for configuration.

Is this normal?

I would've thought it would see the home directory attribute as a "modified"?
