Permission issue in calling EJB from MDB
by valsaraj pv
Hi,
We have recently switched from JAAS to Keycloak. Application is JavaEE
application with EJBs & MDBs.
Set keycloak login module in WildFly to propagate user from wen to EJB & it
worked.
But facing issue when an EJB is called from MDB. There is anonymoius user
in MDB when message received. So that user don't have permission to invoke
EJB protected by:
> <s:security>
> <ejb-name>*</ejb-name>
>
> <s:missing-method-permissions-deny-access>false</s:missing-method-permissions-deny-access>
> <s:security-domain>keycloak</s:security-domain>
> </s:security>
In JAAS version, we have programmatic login using dedicated mdb user.
loginContext = new LoginContext("ldap", new CallbackHandler() {
@Override
public void handle(Callback[] callbacks) {
int len = callbacks.length;
Callback cb;
for (int i = 0; i < len; i++) {
cb = callbacks[i];
if (cb instanceof NameCallback) {
NameCallback ncb = (NameCallback) cb;
ncb.setName(mdbuserName);
} else if (cb instanceof PasswordCallback) {
PasswordCallback pcb = (PasswordCallback) cb;
pcb.setPassword(mdbUsrPass);
}
}
}
});
loginContext.login();
This have user with required permission. Since now moved to Keycloak, this
code will not work. What is the option to prevent permission issue in
calling EJB from MDB?
Thanks!

Programmatically login as a user
by valsaraj pv
Hi,
I have web application login via Keycloak working fine. But for a
background processing like reading messages from a queue, need to login as
a dedicated queue user behind the scenes. For this we can't redirect to
login page. Earlier it was done pro grammatically by using JAAS login
context and passing login module & credentials. Now when we switch to KC,
what is the appropriate model to do this?
Please advice!
Thanks!
