Data input by this add-on at the user profile are stored as the user meta data at the ‘wp_usermeta’ DB table with ‘wp_ure_’ prefix.

Is there any reason it should be cleared when the users role is updated/changed?

I don’t see such reason in general. It could be possible just in case ADI plugin fully clears user meta data during its data update process. I will look into this plugin code and let you know if I find something. I could not test it myself as I don’t have AD server available for testing.

I work currently on the ‘posts edit restrictions’ for roles. It will be available soon.
