Before update please read carefully the full announcement.
CentOS 7.4 is out with a major rebase of most of RPMs.
See upstream release notes: https://wiki.centos.org/Manuals/ReleaseNotes/CentOS7
The list of known issues is quite long this time.
Upgrade and rescue
This procedure applies to any NethServer 7.3 installation, even downgraded or broken ones.
yum --enablerepo=nethforge update
Then, be sure to have installed patched
rpm -q sssd-libwclient
The output must be:
At the end, reboot the machine.
Original post below
Samba authentication with AD is broken
When NethServer is joined to an Active Directory (Samba or Microsoft, local or remote), authenticated access to Samba shared folders doesn’t work.
There isn’t a working patch yet, Red Hat is working on it, and Fedora already has a fix but can’t be applied to CentOS right now.
Enable guest access for shared folder and access without password.

YUM installs 32bit packages
This is a cosmetic bug: when upgrading from CentOS 7.3 yum will install additional unused packages.
When updating, use this command:
yum --exclude=\*.i686 update
Anaconda installation may fail on md devices (FUTURE)
This issue may affect future ISO based on CentOS 7.4.
The bug does not affect NethServer right now.
Possible read-only root filesystem
After upgrade to CentOS 7.4, if the machine is rebooted, the root filesystem could be mounted in read-only mode only if nethserver-samba is installed.
Install the new packages before rebooting:
yum --enablerepo=nethserver-testing update nethserver-samba
