The majority of identity web services are deployed in the Mobile Communications industry. For server-side web service providers OpenSSO Enterprise provides a comprehensive solution for ID-WSF. However, solutions for Liberty enabled clients do not provide the same degree of coverage. For example, the Client SDK is not J2ME-compatible and will not work with mobile devices that typically use Midlets to invoke Identity Web Services. Also, the OpenSSO Enterprise ID-WSF does not implement all profiles for the Liberty-enabled user agent or device (LUAD) clients.
