[Samba] Samba 4.5.5, Bug#12600, & those dangling links

Mon Mar 6 13:56:41 UTC 2017

I have updated one of my S4 DCs to 4.5.5, somewhat excited about the  
line in the ChangeLog

  * Bug #12600 - dbcheck does not find or fix dangling links on live objects

Do I misunderstand the scope of this bug?

# samba-tool dbcheck --cross-ncs --fix --reset-well-known-acls
...

It appears it still does not remove the dangling link.
