AuthorizationLoopException when calling NTLM protected Web Service in LTS 12

Alexander Suter

You might encounter issues with web service clients interacting with NTLM-protected web services in LTS 12. While not in every scenario, there is a possibility of facing an AuthorizationLoopException.

This issue arises because, after upgrading the CXF library, it now defaults to using the JDK HTTP Client. This appears to be a bug and has already been reported to the CXF team. As a workaround, you can configure the appropriate Java system property in the jvm.options file.

This fix will be available in 12.0.1.

This was only a problem if you have set web service client property NTLM.challenge explicitly to false, which means, that we do not had any problems with the default configuration.
