Spring Security Kerberos/SPNEGO Extension

[pmularien]

Make sure your browser and the application [running Spring Sec] are on separate machines, otherwise the browser will try to use NTLM and not SPNEGO.

Hi
I am following the exact steps as mentioned in spring security kerberos tuorial but I seem to get the following error when validating kerberos token:
Found key for HTTP/my-key@MYDOMAIN
Entered Krb5Context.acceptSecContext with state=STATE_NEW
>>> EType: sun.security.krb5.internal.crypto.ArcFourHmacEType
Checksum failed !
WARN : org.springframework.security.extensions.kerberos.w eb.SpnegoAuthenticationProcessingFilter - Negotiate Header was invalid: Negotiate YIIQs....

Any pointers how to resolve this error?

Thanks

Does your problem with "Checksum failed" have been resolved?

Got the same:
>>> EType: sun.security.krb5.internal.crypto.ArcFourHmacEType
Checksum failed !

The problem appears in IE only. Firefox and Chrome work fine.
And also Single Sign-On is not working for me.
