Release Announcements
=====================
This is the first pre release of Samba 4.16. This is *not*
intended for production environments and is designed for testing
purposes only. Please report any defects via the Samba bug reporting
system at https://bugzilla.samba.org/.
Samba 4.16 will be the next version of the Samba suite.
UPGRADING
=========
NEW FEATURES/CHANGES
====================
Certificate Auto Enrollment
---------------------------
Certificate Auto Enrollment allows devices to enroll for certificates from
Active Directory Certificate Services. It is enabled by Group Policy.
To enable Certificate Auto Enrollment, Samba's group policy will need to be
enabled by setting the smb.conf option `apply group policies` to Yes. Samba
Certificate Auto Enrollment depends on certmonger, the cepces certmonger
plugin, and sscep. Samba uses sscep to download the CA root chain, then uses
certmonger paired with cepces to monitor the host certificate templates.
Certificates are installed in /var/lib/samba/certs and private keys are
installed in /var/lib/samba/private/certs.
REMOVED FEATURES
================
No longer using Linux mandatory locks for sharemodes
====================================================
smbd mapped sharemodes to Linux mandatory locks. This code in the Linux kernel
was broken for a long time, and is planned to be removed with Linux 5.15. This
Samba release removes the usage of mandatory locks for sharemodes and the
"kernel share modes" config parameter is changed to default to "no". The Samba
VFS interface is kept, so that file-system specific VFS modules can still use
private calls for enforcing sharemodes.
