Nick Couchman commented on GUACAMOLE-367: ----------------------------------------- {quote} Could your CAS server perhaps be set up incorrectly, responding with HTML from an endpoint which CAS expects to respond with XML? {quote} I routinely use the Guacamole CAS extension with CAS SSO logins, and am not seeing this message anywhere in my log files, for either Guacamole or CAS. This is two different installations, with two different versions of CAS (one 4.2.x and one 5.0.x). So, not sure what's going on, Kevin, but, as Mike points out, there's no reason that the CAS XML validator should be trying to validate the HTML on the Guacamole home page. > Missing self closing tag in Link element > ---------------------------------------- > > Key: GUACAMOLE-367 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-367 > Project: Guacamole > Issue Type: Bug > Components: guacamole-client > Affects Versions: 0.9.13-incubating > Environment: Ubuntu 16.04 > Tomcat 8 > Reporter: Kevin Chan > Priority: Trivial > > Java error: > {code:none} > [http-nio-8080-exec-164] ERROR org.jasig.cas.client.util.XmlUtils - The > element type "link" must be terminated by the matching end-tag "</link>". > {code} > app missing closing tag on the following element: > {code:html} > <link rel="stylesheet" type="text/css" href="app.css?v=0.9.13-incubating"> > {code} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
