Hi Florin,

the KPN of the J2EE Engine is this:

host/<fully_qualified_J2EE Enginehostname>@<DOMAIN_NAME>

after you map the KPN of the J2EE Engine to a ADS user ID with ktpass, you then map Service Principal Names (SPN) for the J2EE Engine KPN. On a ADS you use setspn for this purpose and the SPN is in this:

http/<fully_qualified_J2EE Enginehostname>@<DOMAIN_NAME>

(note that http denotes the service type)

For further info, see the J2EE Engine docu here:
