samba - Jan 2017 - samba 4.4.4 Bug access based share enum = yes not work It does not work with many shares

I have a server with a lot of shared folders. (1600) To make life easier 
for users I need to show them just the ones that they can use.
So I used access based share enum = yes for all sections.
Until about 900 shares all work well .. but with a greater number of 
sections happens that all the shares are shown to all users regardless 
of the access rights.

Samba Version 4.4.4 on Centos 7.
