1. The username or password is incorrect 2. You are not authenticating against the correct identity provider. 3. Your account has been disabled/locked out
To address each situation:
1. The username or password is incorrect
You will need to confirm you are using the correct ID and password for your account. It is important to note that the password is case sensitive. If using the internal IDP you can also reset the user account password via the policy manager.
2. You are not authenticating against the correct identity provider.
You will need access to the policy manager to view the authentication policy, OTK User Authentication. In newer versions of the OTK, 4.x, the customizations will be stored in the policy #OTK User Authentication.
By default, this uses only the Gateways internal identity provider. If it has been customized you will need to confirm the branching logic to see which IDP is being used and in what order.
3. Your account has been disabled/locked out
Depending on your IDP, you may need to work with the administrator of those systems to confirm you account status. If you are using the Internal IDP you can view the users properties in the policy manager and make sure the account is enabled.
