Kerberos - Cannot find key of appropriate type to decrypt AP REP - RC4 with HMAC

Question

I\'m trying to setup SSO for Java WebApp using Kerberos/SpNego. I\'m using:

• Java 1.7u67
• org.springframework.security.kerberos 1.0.0.RELEASE

Answer 1

We also got a Invalid argument (400) - Cannot find key of appropriate type to decrypt ... error.

This can simply be thrown if the path to the keytab is wrong (in our case, we forgot we got a docker volume mapping there).

So, be sure the keytab path is the right one, as this could fire this weird exception.
