SSSD - System Security Services Daemon

Introduction

SSSD provides a set of daemons to manage access to remote directories and authentication mechanisms such as LDAP, Kerberos or FreeIPA. It provides an NSS and PAM interface toward the system and a pluggable backend system to connect to multiple different account sources.

More information about SSSD can be found on its project page - https://github.com/SSSD/sssd.

Downloading SSSD

SSSD is shipped as a binary package by most Linux distributions. If you want to obtain the latest source files, please navigate to the Releases folder on GitHub.

We sign release tarballs with our gpg key (id C13CD07FFB2DB1408E457A3CD3D21B2910CF6759) since April 2022. For convenience, the key is also uploaded to keys.openpgp.org keyserver. You can import the key using:

$ curl -o sssd.asc https://raw.githubusercontent.com/SSSD/sssd/master/contrib/pubkey.asc
$ gpg2 --import sssd.asc

or

$ gpg2 --keyserver keys.openpgp.org --recv-keys C13CD07FFB2DB1408E457A3CD3D21B2910CF6759

And verify the signature with:

$ version=x.y.z
$ curl -o sssd-$version.tar.gz https://github.com/SSSD/sssd/releases/download/$version/sssd-$version.tar.gz
$ curl -o sssd-$version.tar.gz.asc https://github.com/SSSD/sssd/releases/download/$version/sssd-$version.tar.gz.asc
$ gpg2 --verify sssd-$version.tar.gz.asc sssd-$version.tar.gz
