It turns out that the problem is almost certainly a systemd + NIS + PAM
issue also occurring upstream in CentOS 8, not only in OpenVZ containers,
as discussed here:
https://github.com/systemd/systemd/issues/12702
This appears to be still unresolved to date.
Enabling nscd as a work-around seems to alleviate the login delays (most
of the time).
Thank you,

Hello,
in a Centos 8 container installed from the template
centos-8-x86_64-ez-7.0.0-6.vz7
and configured as an NIS client:
user login by ssh is delayed by 15 to 30 seconds and accompanied by the
following error messages:
systemd[797]: Failed to create
/user.slice/user-10042.slice/user@10042.service/init.scope control group:
Permission denied
systemd[797]: Failed to allocate manager object: Permission denied
This appears to be related to the fact that /sys/fs/cgroup/user.slice does not
exist and /sys/fs/cgroup is mounted read-only:
# mount | grep cgroup
none on /sys/fs/cgroup type tmpfs (ro,nosuid,nodev,noexec)
Is this a known problem, and is there a fix or work-around?
Thanks, Peter S.
