Thanks for all the info. I think I will go the trust route with IPA 4.1 and see 
what happens (in a test environment first of course.)

So with winsync I will have the 2000+ users in IPA.

Within IPA I have several high risk/impact groups of servers and many low.

For the low risk/impact servers and most desktops they can trust what AD tells 
them.  For the high risk/impact servers/applications we do not want to reply on 
AD for any authorisation so permissions for these will be isolated from AD 
inside IPA.  The idea is if we lose AD or IPA we should not lose both via any

c) You might be able to do both winsync and trusts at the same time then that 
is simpler provisioning. ie a user gets created in AD and automatically gets 
created in IPA ready for you to put in the user group you want.

I am not sure this is the best solution really.
Trust and sync do not help each other. The fact that you have trust does not 
help you to provision users the way you describe.


They achieve different things.   How otherwise do I get 2000+ AD users into 
IPA?   To me winsync allows automated provisioning of users into IPA via AD, 
this greatly reduces manual effort.

That I get. I do not understand how trust helps you in this case.


Thank you,
