SSO - SAPGUI 730 - Different Languages

Hi,

I installed a simple Kerberos SSO configuration.

But now I don't have the Option to switch between the SAPGUI logon language, even I change the parameter via SU01.

Is there no option to choose an individual language, or am I blind?

What is the best way to change the language during the logon, like I changed this without SSO?

Thanks for any help!
