Hi In order to use Shibboleth with Koha 20.11 on Debian GNU/Linux 10 I searched for information about the necessary configuration. The Koha manual doesn't say anything about Shibboleth, but I found https://wiki.koha-community.org/wiki/Shibboleth_Configuration which seems to be the only source of information on this. I followed the information until section "Enabling Shibboleth for your Virtualhost" where it says "Important: Before moving on from this section, you should be able to visit this address and see an xml file download, with no errors shown in your browser: https://kohaserver.yourdomain.example.com/Shibboleth.sso/Metadata" Command "shibd -t" says: overall configuration is loadable, check console or log for non-fatal problems According to https://github.com/Koha-Community/Koha/blob/master/C4/Auth_with_shibboleth.p... I inserted the following into the Apache configuration file <instance>.conf to tell Apache to allow Koha (with Plack running) to authenticate via Shibboleth: <Location /> AuthType shibboleth Require shibboleth ShibUseEnvironment Off ShibUseHeaders On </Location> Replacing "kohaserver.yourdomain.example.com" with the actual domain I tried all sorts of configuration but all I ever get is just the following message instead of the expected XML: Sorry, the requested page is not available Error 404 What may be the cause for this? Is maybe the directory/file "Shibboleth.sso/Metadata" not existing, but how to create it? Best wishes: Michael -- Geschäftsführer · Diplombibliothekar BBS, Informatiker eidg.
