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:
- Red Hat Enterprise and CentOS 7/8
- SUSE Linux Enterprise Server 12SP5
See the SystemRequirements page for more detail on this.
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.
RHEL 6/7. CentOS 6/7
Information about SELinux
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.
from the actual web server machine itself. You MUST use "localhost" as the hostname or it WILL NOT WORK by default. If this test is successful, then the software is ready for further configuration.
You can also access the Status handler from other clients or using a non-localhost name, but only if you change the
acl parameter in the configuration to permit your client address or remove it entirely to open up access to anybody. The ACL is present by default because the Status handler can return some arguably sensitive information about your configuration.
Now you can progress to the GettingStarted material. Once you've actually configured the SP with its own settings and metadata from at least one IdP, in order to check that the SP is "working":
- Protect a directory by requiring a Shibboleth session. Often, this is already done by default for the location "/secure".
Next, you typically place a script inside the protected directory that dumps the web server environment. With PHP for example you could in the easiest case just place a script there with the following:
For an IIS deployment, an example ASP.NET script:
Make sure that the Shibboleth-supplied variables are present. If there is a non-empty variable called Shib-Application-ID, you successfully authenticated and have a valid session. However, you also should check if there are other non-empty Shibboleth variables defined in the attribute-map.xml file. If there are no variables like mail or givenName or surname, the IdP probably releaseed no attributes. In either case, have a look at the shibd.log and transaction.log files.
