[Samba] Bug number for an old commit

[John Mulligan]

Hi Samba team, 

Digging through some old code and commits while trying to understand some ACL 
related behavior we found the following:

https://git.samba.org/?p=samba.git;a=commitdiff;h=6dcbb84d485b8a8ccf0c3a70d9f5f7e951aaf1c6

While the commit message itself provides some context the subject mentions 
fixing "one of the last two bugs with the full Windows ACL support" without 
referring to a bug number. I was hoping a dev, perhaps Jeremy himself, might 
remember what bug itself was.

Thank you.
