Subject [jira] [Created] (DIRSERVER-1635) Exception when obtaining service ticket and aes256-cts-hmac-sha1-96 encryption is used
Date Wed, 20 Jul 2011 15:34:58 GMT
Exception when obtaining service ticket and aes256-cts-hmac-sha1-96 encryption is used
--------------------------------------------------------------------------------------

                 Key: DIRSERVER-1635
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1635
             Project: Directory ApacheDS
          Issue Type: Bug
    Affects Versions: 2.0.0-M1
         Environment: * ApacheDS Trunk as KDC, encryption is set to "aes256-cts-hmac-sha1-96".
* Service: Apache HTTPD 2.2 with mod_auth_kerb
* Client: Linux with MIT Kerberos and Firefox 5

            Reporter: Stefan Seelmann


The client accesses a SPNEGO protected website. When obtaining the service ticket the exception
below is thrown.

When using "des-cbc-md5" encryption no exception is thrown and authentication works. I didn't
test other encryption types, but they should be tested.
