Cloud computing environments are multi domain environments in which each domain can use different security, privacy and trust requirements. A key issue concerning IDM in clouds is interoperability drawbacks that could result from using different identity tokens and identity negotiation protocols. Existing password-based authentication has an inherited limitation and poses significant risks. An IDM system should be able to protect private and sensitive information related to users and processes. How multi-tenant cloud environments can affect the privacy of identity information isn't yet well understood.
