Seems like all remote calls have to be authenticated by remoting-connector.
This is the key <connector name="remoting-connector"
socket-binding="remoting" security-realm="TutorialRealm"/> where
whole jboss ejb remote access is tied to a single app realm. Seems like a mess. If you
have multiple apps on the same server with own security, maintaining acces to them with
remote client is going to be nightmare.
Application login module must have <module-option name="password-stacking"
value="useFirstPass"/> to piggy back on cached Principal/Credentials
If security realm (ApplicationRealm by default) is removed from remoting-connector, there
is no way to authenticate ejb remote call.
Tried multiple approaches
1)
jndiProperties.put(InitialContext.SECURITY_PRINCIPAL, "user");
jndiProperties.put(InitialContext.SECURITY_CREDENTIALS, "pass");
2)
org.jboss.security.client.SecurityClient
3)
org.jboss.security.auth.callback.AppCallbackHandler
User credential set by above means do not get to java ee security context and random UUID
values are used on server, or $local if
setting SASL_DISALLOWED_MECHANISMS=JBOSS-LOCAL-USER not used
A frequently refernced link from jboss7 docs
https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+...
https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+...
is not sufficient to make your remote clients work because it leaves the server
configuration part out of discussion.
Frustrated after fighting this for the thrid day in the row.

My workaround for this was to put a jar file with a dummy login module that just let
authentication requests pass, considering that other security-domains are enabled in
EJBs.
Application login module must have <module-option name="password-stacking"
value="useFirstPass"/> to piggy back on cached Principal/Credentials
That didn't work for me in JBoss 7.1.1. Do I miss other configurations for making
cache to work ?

Daniel,
I use Jboss 7.1.0. password-stacking will work if you have more than one LoginModule. Say,
you leave security realm for remoting unchanged (ApplicationRealm configured by
application-users.properties), Then org.jboss.as.security.remoting.RemotingLoginModule
will place principal in the sharedState map maintained by
javax.security.auth.login.LoginContext. Then your DatabseServerLoginModule gets its turn
it will pick the pricipal cached by RemotingLoginModule. If <module-option
name="password-stacking" value="useFirstPass"/> is enabled.
Your suggestion for dummy LoginModule is good. There you can place principal/credential
supplied by remote client(remote.connection.default.username/password) into sharedState
which in turn will be picked up by any other LoginModule in the array of applications
deployed on this jboss instance.
I see configuration could be like this
| | <security-realm name="ApplicationRealm"> |
| | <authentication> |
| | <jaas name="my-dummy-domain"/> |
| | </authentication> |
| | </security-realm> |
| | <security-domain name="my-dummy-domain"
cache-type="default"> |
| | <authentication> |
| | <login-module code="MyDummyLoginModule"
flag="required"> |
| | <module-option name="password-stacking"
value="useFirstPass"/> |
| | </login-module> |
| | </authentication> |
| | </security-domain> |
| | <security-domain name="myRealDomain"
cache-type="default"> |
| | <login-module code="Database"
flag="required"> |
| | <module-option name="password-stacking"
value="useFirstPass"/> |
| | <module-option name="dsJndiName"
value=""/> |
| | <module-option name="principalsQuery"
value="select password ..?"/> |
| | <module-option name="rolesQuery" value="select
ur.role, 'Roles' from ..."/> |
| | </login-module> |
| | </security-domain> |
Pls, let me know if you use your dummy loginmodule in a similar way
Andrei

Hello Andrei,
I didn't had the time to handle this upgrade to JBoss 7 this last few days. Indeed I
use my dummy login module in this way, without this option:
<module-option name="password-stacking" value="useFirstPass"/>
for it.
But this option is enabled in my real login module and the multiple call to EJB problem
persists even when calling methods remotely or locally from a war.
The problem with multiple calls to the EJB as I understood it will be solved in 7.1.2
version.
