Just to be sure did you followed these steps[1]?
If yes and it don't work, it would be nice if you can share a properties 
files you have and engine.log(the part when engine starts). Please also 
ensure twice you have correct permissions on properties files, keytab 
and apache confiig.

Also ensure your browser is correctly setup. Example for firefox[2].

It don't work only for API or for UserPortal and Webadmin as well? Or 
you set it up only for API?
