There's not enough logs. The invalid/unmapped path is a bit annoying and should be fixed somehow I guess, but it's not the cause of your problem and is rather harmless.
But you should have seen in logs at login time stuff like:
Debug: Namespace : type=shared, prefix=shared/%d/%n/, sep=/, inbox=no, hidden=no, list=children, subscriptions=no location=maildir:%h/Maildir:INDEX=~/shared-index
