Docker on Windows: drives sharing hint

Related to Docker for Windows (as far as I know), short hint for drives sharing: if you use AD account to secure workstation, after password change drive sharing stops working. You need to go to Docker settings, un-share drives, Apply, then share them again (providing new credentials). Weird, does it store my password somewhere in it's guts? PS: eventually you may need to remove the image you were using and download/rebuild it again.
