Hi Ric:

Could it be a cookie issue?  Some systems are better at handling these
than others.  Here I often have to do it manually especially when I am
dealing with different usernames.  Something like…

xauth add remote.hostname/unix:110  MIT-MAGIC-COOKIE-1  d4hexgibberish

If so, then it is not an ESS issue.
