Http Login Forms and Active Directory Authentication Failures

We are planning to move from the domino http password to AD authentication for iNotes, Quickr and Sametime using DA LDAP and AD attribute.One final issue we have is with the login forms for these applications. (We use domcfg and the usual suspect login forms for the apps)

If the AD user account is locked, expired, disabled or when a bad password is entered the results always display as “Invalid password or username”.

I have tried searching but I have not come up with any help to assist in getting a valid response back from these apps for the account status. ex: “Account locked out”…

Can anyone help?
