Hello,
As the previous post described, Centrify is not affected by SambaCry as Centrify doesn't ship Samba. Centrify ships a solution called ADBindProxy to integrate the OS/Open Source version of Samba with Centrify.
The latest release of Centrify ADBindProxy supports stock Samba version 4.x. Centrify strongly recommends customers to apply the latest security patches from Samba first before deploying Centrify ADBindProxy.
Centrify has published KB-8772: Centrify Recommendations for Samba security alert - CVE-2017-7494 (SambaCry).
Regards,
