I use this (unsupported) configuration with no problem at all by configuring

I setup a multicast IP in /etc/opt/SUNWut/auth.props, as such:
# Enable Multicast
# Flag to enable/disable use of multicast in group manager.
# If disabled, group manager will use broadcast.
enableMulticast = true
# Multicast Address
# Multicast group address used by group manager.
# If multicast is enabled, every interface joins this multicast group.
multicastAddress = 239.xx.x.x
# Multicast Time-to-Live
# Time-to-live parameter for forwarding multicast packets.
# If set above one, keepalive messages can pass through routers.
multicastTTL = 10
Make sure the mulicastAddress you define is the same on all of your servers,
and that the group signature has been set properly.
Did you use private interconnects, or were your Sun Rays on routable
segments of your network? It's the routed *private interconnect*
scenario that is not supported. Multicast is the least of the problems
in that particular case.
