Hi Gurus,

I am a newbie with Oracle Identity Management stack 11g.

I want to implement a single sign on solution for which I have installed and configured

1) OID
2) OAM
3) OHS with WebGates
4) OIM

I was trying to implement an external form based login page, I have managed to write a simple HTML base login page which would authenticate user.
I am trying to do away with simple HTML based login application unless I meet some roadblocks which would need me to write the login using JSP etc.

In the login page, I want to implement 2 functionalities

1) After wrong password message should be error displayed

Although after wrong credentials in URL I get something like error
error_code=OAM-1001 which I can use to show my error message I could not find a list of such error code and their meaning. (In one of the threads it said it is part of some JAR but not sure which one)
Does anybody know the JAR name or any documentation for the same?

2) Warning showing next wrong attempt will lock the account and if the account is locked then should show account locked message.
As oracle access manager integration guide suggests http://download.oracle.com/docs/cd/E14571_01/doc.1111/e15740/idmint.htm#CACBBIDI

1. Using a browser, a user tries to access an application URL that is protected by Oracle Access Manager.
2. Oracle Access Manager Webgate (SSO Agent) intercepts the request and redirects the user to the Oracle Access Manager login page.
3. The user submits credentials that fail Oracle Access Manager validation. Oracle Access Manager renders the login page and asks the user to resubmit credentials.
4. The user's unsuccessful login attempts exceed the limit specified by the policy. Oracle Access Manager locks the user account and redirects the user to the Oracle Access Manager Account Lockout URL, which displays Help Desk contact information.
5. The user contacts the Help Desk over the telephone and asks an administrator to unlock the account.
6. Oracle Identity Manager notifies Oracle Access Manager of the account unlock event.
7. The user attempts to access an application URL and this event triggers the normal Oracle Access Manager single sign-on flow.

In my assembly I have password policy in OID, after 3 tries it locks the account when I test with LDAP browser.
How do I implement account lock warning and password lock status on login page because access manager credential collector does not give me any other error or information?
