I guess I deleted some of the earlier emails in this thread, but which version
of Solaris are you running and, if it's Solaris 9, are you using the bundled SSH
that comes with Solaris 9?
If you're using the bundled SSH with Solaris 9 (or 10), the *server* config file
lives in /etc/ssh/sshd_config, not the other paths you quoted. Just to make
sure it's clear, this file lives on the Solaris side of things.
You can verify which version is being run by using ssh from the Mac to the
Solaris box and then typing "pgrep -lf sshd". If it lists /usr/lib/ssh/sshd
then you are using the Sun-supplied SSH in which case you need the path I
mentioned above.

This looks like *client* configuration options in which case this file would
live on the Mac. At first glance the options look OK, *except* that
"TrustX11Applications" does not appear in any of the documentation or public
sources. So you may want to remove this.
One thing you can do to debug this is to type the following on the Mac:
ssh -X -v solarishost
You should see a lot of debug output, but near the end after you enter your
password it should say something like:
debug1: Requesting X11 forwarding with authentication spoofing.
If you don't see anything saying "Requesting X11" then the problem is on the
client side. If you do then it's on the server side...
And incidentally it looks like the debug output does not say whether the request
is granted or not which is a little unhelpful.
