Can't connect on Solaris

I've been unsuccessful at getting the new Solaris client operational.

When executing the following from the command line:

./boinc -attach_project http://einstein.phys.uwm.edu 159376

I get the following result (error):

BOINC failed to log in to http://einstein.phys.uwm.edu/.
Please check your account key and try again.

My account key is what's listed under my setup on the E@Home webpage.

Any idea what could be wrong?
