201 Authentication Error

Problem

When the credential policy for a user is set to “User Must Change at Next Login,” the user is prompted to change their PIN with the message [209]-Change PIN. However, when the user enters the new PIN, the [201]-Authenticaiton Error message displays and the user is not able to log in.

Solution 1

Reset the user password/PIN in order to resolve the issue. Go to the user page and click the Edit Credentials button located near the password. Also, make sure the locked by the administrator field is unchecked.

This isssue can also occur if the end users are using the alphanumeric characters to log in to extension mobility since it is configured to use only numeric characters during log in. Go to the Extension Mobility service parameter Alphanumeric User ID and check if it is set to False. If it is, make sure that the end users are using only numeric characters during log in.

Solution 2

When the user tries to log in to Extension Mobility, the userid and PIN are validated through the Identity Management System (IMS). If the IMS returns a Change PIN error, the current implementation of Extension Mobility displays an error message on the phone to change the PIN. Users must change their PIN though the ccmuser pages and then attempt to log in. It is not possible to change the PIN from the phone.

Error: Login is unavailable (205)

Problem

You receive this error message when you try to log in to Extension Mobility:

Login is unavailable (205)

Solution

In order to resolve this issue, associate the phone to the Extension Mobility Controlled Profile.
