Whoops, sorry if you all received this more than once. I accidentally
submitted this to the old dev mailing list.
I'm trying to setup a new CAS server that delegates authentication but also
uses U2F multifactor authentication.
Delegated authentication works fine, but when I try to enable U2F MFA I'm
getting errors:
Caused by: org.thymeleaf.exceptions.TemplateProcessingException: Error
during execution of processor
'org.thymeleaf.spring4.processor.SpringInputGeneralFieldTagProcessor' (
template: "casU2fLoginView" - line 53, col 78)
at org.thymeleaf.processor.element.AbstractAttributeTagProcessor.
doProcess(AbstractAttributeTagProcessor.java:117) ~[thymeleaf-3.0.9.RELEASE.
jar:3.0.9.RELEASE]
{...}
Caused by: org.springframework.expression.spel.SpelEvaluationException:
EL1008E: Property or field 'token' cannot be found on object of type
'org.apereo.cas.authentication.principal.ClientCredential' - maybe not
public or not valid?
Seems to me instead of a `U2FTokenCredential` being set as the "credential"
variable for the template, the Delegated Authentication related
`ClientCredential` is being used.
I was able to get it to work by modifying U2FAccountCheckRegistrationAction
to include:
WebUtils.putCredential(requestContext,new U2FTokenCredential());
I would *love* to submit a pull request to fix this but I know this isn't
the correct fix. I'm not even sure if this issue is specific to U2F or all
MFA after a delegated authentication.
Can anyone offer suggestions on where I should look at to fix this
correctly? Unfortunately I'm still new to the CAS codebase.
Thank you all.
- Danny
