ISE 1.2 Guest portal user cannot change their passwords

Question

I have a WLC 5508(version 7.6) and a server installed  the ISE (version 1.2.1.198)，Now we configured the CWA，Use guest portal as an employee and guest login url，We can use the manually create internal user and password successfully logged in, and we set up allow guest users to change password in Multi-Portal, but the user can not change the password in the guest portal ,I suspect the change password option on the Guest  Portal actually works? Can anyone tell me how to change their own username password in the guest portal ?

Answer 1

Requiring Guests to Change Password
You can allow or require guest users to change their password after their initial account credentials are created by the sponsor. If guest users change their passwords, sponsors cannot provide guests with their login credentials if they are lost. The sponsor must create a new guest account.
You can either allow guests to change their passwords, or you can require that they do it at expiration and at first login. To require internal users using a guest portal to change their password upon their next login, choose Administration > Identity Management > Identities > Users . Select the specific internal user from the Network Access Users list and enable the change password check box.
Before You Begin
Create a Guest portal or modify the DefaultGuestPortal. This setting is specific to each Guest portal.
Step 1 Choose Administration > Web Portal Management > Settings > Guest > Multi-Portal Configuration.
Step 2 Check the Guest portal to update and click Edit .
Step 3 Click the Operations tab.
Step 4 Check either or both options:
Allow guest users to change password
Require guest users to change password at expiration and first login
Step 5 Click Save .
