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.
