CAS 6.4.x with SPNEGO, "Factory method 'spnegoAuthentications' threw exception"

[Thierry MURGUE]

Hi all,

I have a working conf with SPNEGO for CAS 6.2.x (last tried 6.2.8).

I’ve tried for 2 days to do the same with the new 6.4.0 version.

I used the generated WAR overlay from the doc (SPNEGO Authentication / Resources / Generate CAS Server WAR Overlay)

I downloaded jcifs-ext.jar from the CAS codebase (branch 6.4.x) in lib/ (newly created)

I added implementation files("${projectDir}/lib/jcifs-ext.jar") into build.gradle just before spnego-webflow dependency

 

And when I build the project, I have error like this :

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [java.util.List]: Factory method 'spnegoAuthentications' threw exception; nested exception is java.lang.IllegalArgumentException: Location must not be null

 

All files are from the generated overlay, only the few changes explained before.

 

Any help will be very much appreciated.

Thanks in advance,

Best regards,

Hi.

If you could post the entire stack trace, that would help to see what might be misconfigured.

Cheers,

D.

Hi there.

The error points to this line: https://github.com/apereo/cas/blob/master/support/cas-server-support-spnego/src/main/java/org/apereo/cas/config/SpnegoConfiguration.java#L68 where it calls Spring resource loader abstraction to load Kerboros config file and apparently the resource representation of that Kerboros config file is null. That is controlled by this setting -> cas.authn.spnego.system.kerberos-conf

You might want to check that you have correctly specified the value for that property pointing to your Kerboros config file.

Hi Dmitriy, Hi all!

It Works! Thanks a lot.

With 6.2, this setting was not mandatory... Maybe, they should add this in the docs (can't find here : https://apereo.github.io/cas/6.4.x/authentication/SPNEGO-Authentication.html)

Or maybe I didn't look at the right place in the docs.

Thanks you again.

Best regards,
