TokenAuthentication: Action execution disallowed

[Agustín Ezequiel Pereyra]

Hello,

I have configured a basic Apereo CAS instance, and I noticed that Apereo CAS is logging the following message each time someone accesses the Apereo CAS login and logout web pages. It is not an "Error" message, so I guess everything is working: 

  [org.apereo.cas.web.flow.TokenAuthenticationAction] - <Action execution disallowed; pre-execution result is 'error'>  

 Yet, after reading the documentation and the code, I couldn't figure out what it means. From what I've seen in the `TokenAuthenticationAction` class (see https://github.com/apereo/cas/blob/6.5.x/support/cas-server-support-token-webflow/src/main/java/org/apereo/cas/web/flow/TokenAuthenticationAction.java), it is "an action in the webflow that retrieves user data from an encrypted token". But why is it giving me this message?

Some configuration that I have and may be related to this:

`cas.webflow.crypto.encryption.key=<A KEY WE CREATED THROUGHT THE JAR GIVEN BY CAS>` 
`cas.webflow.crypto.encryption.key-size=32` 

Summing up: Could someone please explain me what does the message

  [org.apereo.cas.web.flow.TokenAuthenticationAction] - <Action execution disallowed; pre-execution result is 'error'>  

mean?

Thanks,
