Hello, We're having issues setting up CAS on a new instance of Koha. We have this working on a 3.6.4 server, but we've implemented 3.14.5 on a new server and can't get it to accept the CAS ticket. The CAS server is returning a valid ticket, but the OPAC displays a (not obvious) error: "Sorry, the CAS login failed." The following two lines appear in koha-opac-error_log: [Wed May 21 15:54:41 2014] [error] [client 10.41.57.78] [Wed May 21 15:54:41 2014] opac-user.pl: DBD::mysql::st execute failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 at /usr/share/koha/lib/C4/Letters.pm line 220. [Wed May 21 15:54:41 2014] [error] [client 10.41.57.78] [Wed May 21 15:54:41 2014] opac-user.pl: Can't use an undefined value as an ARRAY reference at /usr/local/lib64/perl5/DBI.pm line 2064. We've set up the CAS options to match the 3.6.4 server, and it sends the request to CAS appropriately, but it won't accept the response. Are we missing something?
