A special note applies to Red Hat Enterprise Linux (RHEL) 7 and probably all future versions: because of Red Hat's licensing restrictions, it's impossible for the build service to target Red Hat RHEL 7 directly. However, CentOS is an identical system, and the packages for it work on the equivalent Red Hat RHEL versions, so Red Hat RHEL 7 deployments should rely on the CentOS 7 package repository.

Under no circumstances should you attempt to install a set of RPM packages built for/with a different OS or version from your own (apart from the CentOS/RedHat RHEL exception noted above). This will usually lead to unpredictable problems and support issues. Instead, you can rebuild the SRPM packages. |

Red Hat RHEL and CentOS 7.4 include a newer version of OpenSSL, and due to an inadvertent rebuild of one package by the SUSE Build Service, the packages for that OS had to be fully rebuilt, which means they no longer support versions older than 7.4. A full yum update to the new OS will include the update to these packages, but updating to them or installing them from scratch will fail if the OS version is older than 7.4. We apologize for the inconvenience but the problem was impossible to recover from. |

The supported approach is to add a yum repository referencing the Shibboleth Project mirror sites alongside your existing OS-supplied repository. Ths This allows you to manage the Shibboleth packages in a standard way and pick up updates using a single command.
For Red Hat EnterpriseRHEL, the CentOS team provides some material on using yum.
To get a copy of the appropriate repository file for your system, see https://shibboleth.net/downloads/service-provider/latest/RPMS/ for a simple drop down form that will generate a copy for you. Per the note above, Red Hat RHEL 7 systems must use the CentOS 7 repository.

Be careful of accidentally installing both the 64-bit and 32-bit version on a 64-bit server. The yum repository contains both versions for some OSs and the OS will think it can install both. |
