If you are running Self Service Password Reset 3.2 or a prior versions and have the Forgotten Password module configured, you must perform additional steps to stop errors occurring during the upgrade or migration process.
Self Service Password Reset 3.3 and above contains a new configuration option for forgotten password verification methods. If you upgrade without reviewing these new options, when you access the Forgotten Password Module it returns an error of SSPR Error 5006 - The username is not valid or is not eligible to use this feature. (Bug 979153)
To fix the error, you must review the forgotten password verification methods and change these options for your environment.
To review the forgotten password verification methods:
Log in as an administrator to Self Service Password Reset at https://dns-name/sspr.
In the toolbar, click your name.
Click Configuration Editor > Modules > Forgotten Password > Forgotten Password Profiles > default > Verification Methods.
If you have created a different profile, select that name instead of default.
Review the verification methods and change these options for your environment.
Click Save changes.
