RedHat has joined the list of OS vendors that feel that Identity Management is a key offering. They have acquired Identyx, a provider of open source IdM products. This fits nicely with their existing directory server product (which Jackson Shaw and I commented on earlier, here and here).
So now the list of OS Vendors with directory servers and IdM products looks like:
Microsoft -AD, ADAM, ILM, ADFS
Sun – Sun DS, Identity Manager, Access Manager, Federation Manager, Role Manage
IBM – Tivoli DS, TIM, TAM, Tivoli Directory Integrator
RedHat – RedHat DS, Penrose, Velo
