A partner of mine needs to install SimpleSAMLphp plug-in but his Moodle version is 2.6.
The idea is that he provide us users identities as (IdP) from moodle so we can validate users and provide access to our app.
If it is not supported at moodle 2.6 how can we move forward ?
It looks like the plugin has a version available for Moodle 2.6: https://moodle.org/plugins/pluginversions.php?plugin=auth_saml , did they try it?
The better answer though is upgrade Moodle. According to https://docs.moodle.org/dev/Releases#Moodle_2.6 the Bug fixes for general core bugs in 2.6.x ended November 2014 and Bug fixes for security issues in 2.6.x ended May 2015, so there are 4 or more years of security issues fixes built up that have not been applied.
This means that there are likely serious security issues in your partner's running moodle. You can go from 2.6 to 2.7 https://docs.moodle.org/27/en/Upgrading

Then from 2.7 to 3.2 https://docs.moodle.org/32/en/Upgrading
and then from 3.2 to either 3.7 or 3.5 Long-Term Support version if you don't want to update again until May 2021: https://docs.moodle.org/dev/Releases#Moodle_3.5_.28LTS.29
Thanks ! Just one more doubt.
Are "SAML Authentication" and "simpleSAMLphp" two diferent plug-ins ? When I click in the link you have sent I have the impression that my client must install "simpleSAMLphp" plug-in to install "SAML Authentication" plug-in. As he told me he cannot install SimpleSAMLphp plug-in due to his Moodle version which is 2.6, I dont know what to suggest him.
Best.
I had a long reply typed up but the time out ate it.. so shorter version now that I've re-read your initial post and realize you want to use Moodle as an identity provider rather than service provider.
This plugin looks to be the only one that allows you to use Moodle as an IdP: https://moodle.org/plugins/auth_samlidp and yes, it requires Moodle 3.1 - 3.5, so Moodle 2.6 will not work.
simpleSAMLphp is not a moodle plug-in, it's a seperate program you install on the same server as Moodle.
So you need to either upgrade moodle, or find/write another plugin that will work as an IdP for Moodle.. or pay someone to do one of these things.
Upgrading moodle is probably the much easier step
