Remmina (XDMCP) keyboard layout problem

Hi, there!
I installed Remmina on openSuse 12.3. I have a spanish keyboard with keys like ‘ñ’, and ‘Alt Gr’.
I made a remote desktop connection with XDMCP to RedHat machine, but when I use a Terminal on RedHat, the keyboard layout isn’t mapped rightly. (It is mapped as US keyboard.)

When I use

X -query <IP address> :1

to access to RedHat machine the keyboard layout map right.

Do you have any idea?

Thank you, in advance.
