you need to explain to upper management why using IPA your company will
save money. They usually understand that sort of talk.

Write a business case. In the documentation (both from RHEL and from
freeipa.org) you will get plenty of useful info.

Magnify the points where AD comes short for your user case (selinux, sudo,
automounts, service credentials management - having used ktpass.exe I was
amazed at how nice the keytab capabilities are from ipa-, hostgroups, ssh
public key management, ..., the list goes on and on). Explain that *that*
will not change and how much money it will cost your business (admin hours,
security risks, missed compliance).

Explain why the future is in the trust model in ipa v3.

Explain that Windows admins are not expected to run a Windows network
without AD, so why are Linux/AIX admins expected to run a network without a
proper Linux/AIX identity management solution.

I feel your pain and can understand why you are upset, but try not to take
this all personally. In the end, it is not your network.
