I am using Koha 3.16.04.000. I am very interested in getting Koha to use OAuth2 for patron login since we use Google Apps for Education. I have two different instances of Koha running, so I have been testing using the one that is not mission critical. I followed the instructions at http://wiki.koha-community.org/wiki/Alternative_OPAC_logins_RFC#Instructions.... The patch applied and so on, and I added the client ID and secret in Koha. But when I navigate to http://koha.theology-vietnam.org/cgi-bin/koha/svc/googleoauth2 I get Error 500. I looked at the most recent output in the Apache error log: [Thu Apr 16 06:42:07 2015] [notice] Graceful restart requested, doing restart PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/curl.so' - /usr/lib/php5/20090626+lfs/curl.so: cannot open shared object f$ PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/ldap.so' - /usr/lib/php5/20090626+lfs/ldap.so: cannot open shared object f$ PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/xmlrpc.so' - /usr/lib/php5/20090626+lfs/xmlrpc.so: cannot open shared obje$ [Thu Apr 16 06:42:08 2015] [notice] Apache/2.2.22 (Ubuntu) PHP/5.3.10-1ubuntu3.17 with Suhosin-Patch configured -- resuming normal operations [Thu Apr 16 11:27:42 2015] [error] an unknown filter was not added: includes I cannot tell much from this (sorry, my server knowledge is patchy). Has anyone gotten this running on Koha 3.16.04? Do I need to make any changes to the patch? Daniel
