I have tried search the forums to find this info but it seems to be missing. I have installed koha through the koha on ubuntu - packages guide. The installed version is Koha 3.12.03.000 I setup the preferences for CAS authentication in koha administration pages. However two problems I encountered are: The service link that is sent the CAS server by the link on koha OPAC login page does not include the domain. https://{cas_server}:8443/cas/login?service=%2Fcgi-bin%2Fkoha%2Fopac-user.pl What do I have to setup in Patrons on koha for it to begin accepting logins from the CAS server? I added one patron to Koha then use the same person to login to cas and then have the CAS server redirect to koha. Koha then says "CAS login failed". Any help appreciated. -- View this message in context: http://koha.1045719.n5.nabble.com/CAS-Authentication-Explained-tp5764435.htm... Sent from the Koha-general mailing list archive at Nabble.com.
