Re: [jetty-users] migration woes from version 9 to 10 - possible charact

[Bryan Coleman <bryan.coleman@xxxxxxxx>]

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
