I am currently running an IPA 3.3 server on Centos 7. I have 70 IPA

I have been informed that all computer users on our campus must now
authenticate off of the University's Active Directory server,
including all Linux machines. I have been looking through the IPA
documentation and am getting myself confused and not completely
understanding what needs to be done, thus I have some questions.
1.The docs talk about setting up a trust between the IPA server and
the AD server. Will I need to change all of the IPA clients as well
as the IPA server, or do I only need change the server and not have to
touch the clients?
With IPA on Centos 7 you can establish trust and you 6.6 machines should
be capable of picking the trust automatically.
2.Do I even need to set up a full trust relationship just to
authenticate my users with AD?
You have three options:
- Establish trust
- Sync users from AD to IPA
- Drop IPA and go direct AD (but you loose a lot).
We recommend the trust approach and yet it is a full trust but that does
not mean that it is wild west. The trust just means that users can cross
authenticate. But if there is no permissions set (which is the case by
default) the users even if they are authenticated can't do anything. So
if your AD guys a re worried that the trust would open the can of worms
it would not.
3.Since I already have 150 users, will I have to delete their IPA
accounts before setting up the trust? W
Are these users the same as AD users?
If they are you can move to IPA 4.1 and convert them to ID Views to
assign posix data to the AD users and then remove.
Sorry if my questions are a bit basic, but I need some guidance to get
