I've tried it (wrote a little script to test it), and I got the following:
length(usename) == 9 : connect with usename of 9 : failed
length(usename) == 9 : connect with usename of 8 : failed
length(usename) == 8 : connect with usename of 9 : failed
length(usename) == 8 : connect with usename of 8 : succeeded
so it appears not to be working somehow...
