> --------------------------------------------------------------------------------------
>
> 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
> Assignee: Stefan Seelmann
> Fix For: 2.0.0-M2
>
>
> 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.
