Hi,
I'm getting a strange error when running the Onelogin SSO Wordpress
plugin to authenticate users with a CAS with SAML support. I managed
to get the plugin working with simpleSAMLphp so I think the problem
is in the CAS side.
The displayed error message is:
CAS is unable to process this request: "500:Internal Server Error"
Error: org.opensaml.saml.common.SAMLException:
No signature signing parameter is available
I think the problem is some metadata parameter, but I cannot find a working
example to give some light. I configured the service in a JSON this way:
(file name is lvs05saml-10000003.json)
{
"@class" : "org.apereo.cas.support.saml.services.SamlRegisteredService",
"serviceId" : "lvs05saml",
"name" : "lvs05saml",
"id" : 10000003,
"attributeReleasePolicy" : {
"@class" : "org.apereo.cas.services.ReturnAllAttributeReleasePolicy"
},
"metadataLocation" :
"http://HERE_I_PUT_MY_WORDPRESS_URL/wp-login.php?saml_metadata";,
"metadataSignatureLocation" :
"file:/usr/local/etc/cas/certs/ONE_LOGIN_PLUGIN_CERT.pub",
}
Uppercase HERE_I_PUT_MY_WORDPRESS_URL and ONE_LOGIN_PLUGIN_CERT are
substituted by the actual conf values.
I'm basically stucked at this point, so I feel I need some hint to
carry further research and solve this error.
Thanks for your help,
