I had it running a few weeks ago - it was ESX3i before the free
disastrous update. It seemed to work fine, but I haven't used CHAP
authentication. I've since updated the VMWare server to the patched
free version and comissioned it, so for the moment won't be able to
test.

The target was current-i386 of 4.99.59 (or thereabouts) vintage. I use
whole disks as targets:

# extent        file or device          start           length
extent0         /dev/wd0d       0               78533MB
extent1         /dev/wd1d       0               78533MB
# target        flags   storage         netmask
target0         rw      extent0         0.0.0.0/0
target1         rw      extent1         0.0.0.0/0
