Subject: Re: [jetty-users] migration woes from version 9 to 10 - possible
character encoding issue
Thanks for the information.
Yes, I believe it is related to the FallbackAuthenticator as well. I was able
to get the Basic portion of the fallback to work by bringing it in line with
apparent differences from the BasicAuthenticator; specifically, the credential
"space" and charset. I wonder if there isn't something similar with the
Kerberos authentication?
I since tried to temporarily replace the FallbackAuthenticator with the
ConfigurableSpnegoAuthenticator. The result is a "RuntimeException:
GSSException: Failure unspecified at GSS-API level (Mechanism level: Invalid
argument (400) - Cannot find key of appropriate type to decrypt AP-REQ - RC4
with HMAC)". My thought was to get the out-of-the-box
ConfigurableSpnegoAuthenticator to work before using custom code. The odd
thing is the code works fine with jetty 9; however, with jetty 10 the
GSSException keeps coming to the surface.
A few things I was trying to track down:
1) Does jetty 10 use a different set of default encoding types?
2) Is there a way to set libdefaults default_tkt_enctypes and
default_tgt_enctypes programically via the JassConfigurator (i.e.
Configuration)?
3) Do I need to create the keytab file differently?

No.

Look at the tests, see

Finally, no matter how good the architecture and design are, to deliver
bug-free software with optimal performance and reliability,
the implementation technique must be flawless. Victoria Livschitz
