What do you like best?
CA IdentityMinder is a very good product, it allows very easily as a user to approve requests and if configured properly it can automate through workflows a lot of the stuff one used to do manually. Being able to write custom adapters for all kinds of endpoints is also a big plus, especially since now it supports Java which is lie an industry standard if you would.
As a deliverer it is quite difficult to setup, it needs quite a few components but being able to determine graphically the approval workflows is definitely a big big plus. Finding orphaned accounts is also quite simple.
Last but not least, self-service functions for end-users and strong password policy enforcement are two other pros of this solution.
What do you dislike?
As I said above, IdentityMinder is quite heavy on the infrastructure side and requires a lot of work to set it up quite right. Workflows are necessary tasks to get going to avoid doing everything manually which is quite complicated on IdentityMinder.
Also it is not such a good idea having two different repositories to get two-ways synchronization. Design could be simpler.
Recommendations to others considering the product
If you need Identity Management without integrating in a bigger suite it could really be what you need.
What business problems are you solving with the product? What benefits have you realized?
User id management and centralization, clean and controlled identities accross all softwares and systems. All users can now use a single user and password without having a specific SSO solution and without having to remeber dozens of different passwords with different expiration dates.
