Session replication : classcastexception on principal

[Sébastien Letélié <sl...@improve.fr>]

Hi,

	I use a JAASRealm in my context with mys own LoginModule to
authenticate in mys webapp. When I use the cluster for session replication,
I have a ClassCastExecption when the cluster try to serialize the Principal
object. 
	When I look in the source code
(org.apache.catalina.cluster.session.DeltaRequest.setPrincipal(), I see that
they are a cast for the specific catalina principal object :
GenericPrincipal.
	With a JAASRealm you don't use this object for principal, you
precise your own class (userClassName attribute).

	Is it a bug or is my authentication technic is not ok ?
