SSO implementations utilize centralization of all user account information. Depending on environmental
complexity and the age of the systems over which a SSO solution is implemented, it may not be possible to

+change the solution architecture so as to accommodate a new identity management and user authentication system.
Many SSO solutions involving legacy systems consist of a new super-structure that handles authentication on
behalf of the user. The software that gets layered over the old system may simply implement a proxy
authentication system. This means that the addition of SSO increases over-all information systems complexity.
standards, has adopted SAML 1.1 as part of its application framework. Microsoft and IBM have proposed an
alternative specification called WS-Security. Some believe that the competing technologies and methods may
converge when the SAML 2.0 standard is introduced. A few Web access-management products support SAML today,
