Thanks for reply, Jan!
I have enabled SSO as you have said.
But it dont' works still :(
After few experiments I have found the cause of my problem.
My first application uses SSL (it means HTTPS-listener is used).
I have removed SSL from first application and it's works fine!
After login in first application I can login in second without new authentication.
It is new feature in glassfish (because on SJSAS 8.2 it works fine with SSL)? How can I configure it correctly for using first application with SSL?
Thanks.
