We actually rolled out a new project for them recently using Spring framework, and was to a large degree a success. The problem with the system in question is that it would require some what quite a bit of re-architecture to work Spring into the bigger picture. Its on the cards for the coming major release though. The problem has been that the authentication/authorization to large degree is crippled. Crippled in a sense that each user login was bound through data schema and many other parts to only a single user role per user login credentials. So fixing this has been the obvious priority. As one of the requirements that came up is the user SSO (Single-Sign-On), integration with Corporate LDAP support for auth.
