OpenAM : Can't login with custom authentication module - openam

Question

I developed a custom authentication module by following the example and installed into top level realm. OpenAM 11.0.0.
Then I open the test page for my auth module.
The login fails with the error "Login/password combination is invalid."
However, if I open /openam after seeing this error message, it says I am logged-in.
Here is the process code of the AMLoginModule
public int process(Callback[] callbacks, int state) throws LoginException
{
if (debug.messageEnabled())
{
debug.message("Authentication module process() is called. state: " + state);
}
switch (state)
{
case STATE_BEGIN:
// No time wasted here - simply modify the UI and
// proceed to next state
substituteUIStrings();
return STATE_AUTH;
case STATE_AUTH:
return ISAuthConstants.LOGIN_SUCCEED;
case STATE_ERROR:
return STATE_ERROR;
default:
throw new AuthLoginException("invalid state");
}
}
You can see any username / password is accepted. The debug log shows that the module is called correctly.

Please why do I see the error "Login/password combination is invalid." in test login page?

Answer 1

The problem is that you don't have user profile to login. You need to have the username in your datastore which you pass to SampleAuthPrincipal("username") constructor .
#Override
public Principal getPrincipal() {
return new SampleAuthPrincipal("username");
}
This should resolve your problem.
