Welcome Microsoft Identity Manager!
after MMS, MIIS, CLM, ILM and FIM we got a new acronym: MIM - Microsoft Identity Manager.
Perhaps because I never understood why it was called Forefront .. Microsoft thought simpler is better.
So then the only question is why FIM did become MIM and not CIM - Cloud Identity Manager. Perhaps one day we all have just one ID in the cloud and there is no need for identity management anymore. Nice dream.
