NetIQ identity manager is a true enterprise product. Stable, well developed and with all the features you could expect.
It has an easy to use workflow for creating users.
The self-service portal for resetting passwords etc. is easy to deploy.
Has strong user activity monitoring.
Was easy to install on premise
The interface is a bit outdated, a quick overhaul of the interface would mean the world.
It would be nice to be able to customize the self-service portal more.
