hi guys

I wonder if it is(would be) possible to have IPA join AD but
so IPA admin only asks AD admin(s) to do whatever is
required and then s/he does IPA end?
And a reason you would do that is - domains are formally(and
in other ways) separate that AD admin would have to keep
secret and not share any of those AD credentials you would
normally use in IPA to add such a trust.

many thanks, L.

Hi,

it is possible to use a shared secret instead of the AD admin credentials when establishing the trust:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/windows_integration_guide/trust-during#create-trust-shared-secret


Does this address your concern?

That might be exactly it!
I'm trying "one way" and while the command succeeded I saw this:
...

Now I'm trying to ssh to IPA as:

$ ssh a...@ad.priv.dom.local@10.1.1.1

but this fails as if the password was incorrect, which naturally is not true.
Is the problem "one way" trust?
One-way trust with a shared secret is not working currently. Either use
two-way trust with a shared secret or use admin credentials.

If you are interested in the details, just search mailing archives.
