Linux 5.8 made faccessat2() system call available in August 2020. This system call is used now by GNU libc to implement more precisely faccessat() system call. GNU glibc does compile-time check for the kernel version and uses faccessat2() unconditionally in case it is available. If kernel responds with ENOSYS error code, GNU libc will attempt to use older, less flexible, faccessat(() system call. When running on a system where libseccomp does not know about the new syscall, the default action in seccomp filters in Docker and other container runtimes is to respond with EPERM error code. This breaks GNU libc's implementation of the faccessat() function -- as well as other newer syscall implementations (e.g. statx()). libseccomp started to support faccessat2() in July 2020 with https://github.com/seccomp/libseccomp/commit/5696c896409c1feb37eb502df33cf36efb2e8e01 (version 2.5.0: https://github.com/seccomp/libseccomp/releases/tag/v2.5.0) With Ubuntu 20.04 as a host, use PPA abbra/freeipa-libseccomp which provides libseccomp 2.5.0 rebuild from Debian Sid.

FreeIPA Server
FreeIPA allows Linux administrators to centrally manage identity, authentication and access control aspects of Linux and UNIX systems by providing simple to install and use command line and web based management tools.
FreeIPA is built on top of well known Open Source components and standard protocols with a very strong focus on ease of management and automation of installation and configuration tasks.
FreeIPA can seamlessly integrate into an Active Directory environment via cross-realm Kerberos trust or user synchronization.
Benefits
FreeIPA:
- Allows all your users to access all the machines with the same credentials and security settings
- Allows users to access personal files transparently from any machine in an authenticated and secure way
- Uses an advanced grouping mechanism to restrict network access to services and files only to specific users
- Allows central management of security mechanisms like passwords, SSH Public Keys, SUDO rules, Keytabs, Access Control Rules
- Enables delegation of selected administrative tasks to other power users
- Integrates into Active Directory environments
Components
The FreeIPA project provides unified installation and management tools for the following components:
- LDAP Server - based on the 389 project
- KDC - based on MIT Kerberos implementation
- PKI based on Dogtag project
- Samba libraries for Active Directory integration
- DNS Server based on BIND and the Bind-DynDB-LDAP plugin
