Before using the self-service-request samples you must first configure the desired setting for how your self-service system will work. 

The file in question come with the RSA Authentication Manager 8.x SDK that is available in the extras.zip.  Review 000065842 - How to download RSA Authentication Manager 8.x full kits and service packs from RSA Community for steps to download.

These settings are found in the Security Console under Setup > Self Service Settings > Manage Authenticators in RSA Authentication Manager 8.x and above

This error can also happen when not using the SDK.  A customer can set up Credential Manager > Manage Tokens to allow users to request one type of token (for example, Desktop PC 4.0) but when the user goes to the Self-Service Console he selects Generic AES.  Since this is not an approved token type, the error message of "This token type is not allowed in UCM" will display.  To resolve the issue simply add the correct token type.
