Andrej Kolontai updated WFLY-13619:
-----------------------------------
Steps to Reproduce:
The problem is reproducible with just one server by making the session store persistent.
My production setup is rather complex so I've created a tiny project just to show the
effect: [https://github.com/andrejkolontai/jaspic-elytron-distributed-demo]
First, get a fresh wildfly distribution (version 20.0.0.Final) and unpack it.
Start it with standalone.sh.
Then, using jboss-cli.sh make the session store persistent:
{noformat}
/subsystem=infinispan/cache-container=web/local-cache=passivation/store=file:add(passivation=false,purge=false)
{
"outcome" => "success",
"response-headers" => {
"operation-requires-reload" => true,
"process-state" => "reload-required"
}
}[standalone@localhost:9990 /] reload
{noformat}
Then create an elytron security domain and connect it to undertow:
{noformat}
[standalone@localhost:9990 /] /subsystem=elytron/security-domain=elytronjaspic:add
{"outcome" => "success"}[standalone@localhost:9990 /]
/subsystem=undertow/application-security-domain=elytronjaspic:add(integrated-jaspi=false,security-domain=elytronjaspic)
{"outcome" => "success"}
{noformat}
The demo project has a servlet, a session scoped cdi bean (counts the requests in a
session) an a rather trivial authenticator which uses AutoApplySession.
To build it, use the gradle wrapper:
{noformat}
./gradlew war{noformat}
The repository has three tags to see the difference between old security subsystem and
elytron.
First, the old security subsystem to ses how it's used to work:
{noformat}
git checkout old-security
Previous HEAD position was 6dad6c3 Changed security domain to the elytron one
HEAD is now at 547cff7 First Commmit
./gradlew warBUILD SUCCESSFUL in 1s
2 actionable tasks: 1 executed, 1 up-to-date
cp build/libs/jaspic.war ~/devel/wildfly-20.0.0.Final/standalone/deployments/{noformat}
{{}}
Verify that the authentication mechanism kicks in:
{noformat}
curl -w '\n' -c cookies -b cookies localhost:8080/jaspic/hallo
<html><head><title>Error</title></head><body>Unauthorized</body></html>{noformat}
call with authentication credentials:
{noformat}
curl -w '\n' -c cookies -b cookies -H "secret: shampoo"
localhost:8080/jaspic/hallo
Hallo Welt 0{noformat}
verify that the authentication state is stored in the session (call without secret):
{noformat}
curl -w '\n' -c cookies -b cookies localhost:8080/jaspic/hallo
Hallo Welt 1{noformat}
reload/restart wildfly
verify the session has survived the reload:
{noformat}
curl -w '\n' -c cookies -b cookies localhost:8080/jaspic/hallo
Hallo Welt 2{noformat}
Now, switch to elytron by changing the security domain:
{noformat}
git checkout elytron-security{noformat}
build & deploy like above
Now do the same procedure but clear the cookies first:
{noformat}
rm cookies
curl -w '\n' -c cookies -b cookies localhost:8080/jaspic/hallo
<html><head><title>Error</title></head><body>Unauthorized</body></html>
curl -w '\n' -c cookies -b cookies -H "secret: shampoo"
localhost:8080/jaspic/hallo
Hallo Welt 0{noformat}
At this point you should see wildfly throwing exceptions. My demo application seems to
work. But my production application would stop working. And the sessions are not actually
persisted. One more effect in production: when a server is restarted, it takes a very long
time for it to come back again because the running server is struggling to serialize the
session data which is not possible while the restarting server is waiting for the cached
session data to arrive. After a timeout, the affected applications would just go into
.failed.
A possible workaround is to make the application non-distributable:
{noformat}
git checkout non-distributable{noformat}
build & deploy again like above. Repeat the test. Everything just works but, of
course, the sessions are not persisted and in production there would be no session
failover.
I could stay with the old security subsystem (like "jaspitest"). But I really
like elytron better and words like "dummy" in a production configuration are
kind of scary.
That's not much of an issue. But I liked the feeling that I could just redeploy an
application or restart a server during normal work hours instead of waiting until midnight
or so.
What is also interesting: it only seems to affect jaspic/jsr375 enabled applications. We
have one application using form authentication backed by an ldap realm which doesen't
seem to have this problem.

Elytron: org.wildfly.security.auth.server.SecurityIdentity not
Serializable
---------------------------------------------------------------------------
Key: WFLY-13619
URL: https://issues.redhat.com/browse/WFLY-13619
Project: WildFly
Issue Type: Bug
Components: Security
Affects Versions: 20.0.0.Final
Reporter: Andrej Kolontai
Assignee: Darran Lofthouse
Priority: Minor
Since the old security subsystem has been deprecated for a while I decided to move my
applications to elytron which worked just fine up to the point where I tried to migrate an
application that is:
* distributed
* uses Jaspic in form of a JSR375 HttpAuthenticationMechanism which has
{{@AutoApplySession }}
In the logs I see stacktraces like this:
{{09:37:22,045 WARN [org.infinispan.PERSISTENCE] (default task-1) ISPN000559: Cannot

Looks to me like it's trying to serialize the session to replicate it to the other
nodes in the cluster and fails because the user identity, which is part of the session
because of AutoApplySession, is not serializable. I have checked the source and it is
really not serializable.
I had no problems with the old security subsystem (i.e. jaspitest).
