[Samba] Winbind crash on Samba 4.7.2

Mon Dec 18 12:48:39 UTC 2017

Hi,

I have a problem with connection to ADS and winbind. I connect to ADS with Samba 4.7.2 and I have a backtrace when I try to change file permissions from Windows client. Below is the backtrace from winbind. Please let me know what kind of information you need. I use a Windows 2012 R2. The permission which I try to set is for "Authenticated Users"
