Single sign on

Hi all,

I have been trying to get SSO with Kerberos working on one of our servers, but when I test the connection I get the following error:

2008-09-02 11:44:59,398 INFO [com.adobe.idp.um.ui.config.ConfigAuthEditAction] This exception stack trace is due to clicking of test button on Kerberos settings page.This is to help in determining wether Kerberos configuration is working fine or not and is not due to andprogram error. The exception that occured while testing Kerberos related config is
com.wedgetail.idm.sso.ConfigException: Could not validate com.wedgetail.idm.sso.password [caused by: com.dstc.security.kerberos.KerberosError: Server not found in Kerberos database]
