-Y switch warning

[Levent Yilmaz]

Hi,

I cannot get some programs (such as Eclipse 3.0.2 from eclipse.org) to
work with -X switch, so I use -Y for ssh connections with X11
forwarding. And, I get this warning message with -Y:

Warning: No xauth data; using fake authentication data for X11 forwarding.

Is this important? Shall/how do I fix it?

thank you
