Shibboleth can be built on most versions of 32- and 64-bit Linux, but is officially supported only on the following distributions at this time, using the RPM packages available from the project's official mirrors:
The official packages are built for, and integrate with, only the Apache (httpd) package that is supplied with the OS. When building from source or SRPM, you can accomodate any version of Apache (or its derivations) that is compatible.
If your distribution supports the RPM package manager, it is strongly suggested that you install using RPMs built for your specific distribution, or by rebuilding the SRPM source packages provided. If this is not possible, you can build from source.
Use the Correct RPM or not at all
Under no circumstances should you attempt to install a set of RPM packages built for/with a different OS or version from your own. This will usually lead to unpredictable problems and support issues. Instead, just rebuild the SRPM packages and make sure you have a repeatable process to incorporate security patch updates promptly.
Upgrading to new releases is handled automatically when RPMs are used, or in the case of a source build when "make install" is run using the same installation prefix. The system prevents configuration files from being overwritten and skips "initial install" tasks like generating keys. In the case of RPM upgrades, services should be appropriately restarted, but with source builds that step has to be done manually.
