Log or trace CAS protocol messages?

[Baron Fujimoto]

Is there a way to log or trace the actual CAS protocol messages exchanged with a client? The logs provide a wealth of details, but not the actual protocol messages exchanged that I've found. We haven't really used Aperero's CAS for SAML yet, but I know the Shibboleth IdP can do this, and there are SAML trace browser extensions as well. I'm hoping for something analogous for the CAS protocol stuff specifically.

Baron,

You can try these loggers set to trace. I think most of the protocol stuff is handled by pac4j.

        <AsyncLogger name="org.apereo" level="${sys:cas.log.level}" includeLocation="true"/>

        <AsyncLogger name="org.pac4j" level="${sys:pac4j.log.level}" includeLocation="true"/>

        <!-- DEBUG outbound and inbound headers and response-->

        <AsyncLogger name="org.apache.http" level="debug" />

And spend the next 2 d crawling through the output ;)

Ray

P.S. careful with credentials in the logs

Thanks, that definitely provides more info, but I think it's still not what I was hoping for, unless it's within the base64-encoded blobs.
