Hi Team, i have a very complex/large AD setup which SSSD successfully integrated the Linux machine onto it.
now after acquiring another company we have to integrate a separate AD forest which is now trusted by our forest root.
I understand that SSSD won't work with external trusts and only support the same forest.
what is the best practice to allow authentication from the new trusted forest.
on my test lab I added the new forest to a new domain section, then used adcli to create a computer account on the new forest. so technically this Linux machine is now joined to two domains klist -k show correct entries for both forests nothing i changed in krb5.conf
my tests are positive and i was able to login both forests from my Linux machine.
is this supported scenario and what is the best practice when having external trust?.
Yes it is so far is the only option how it can be done. There is no HowTo because so far no one actually did this in open and shared. I am not sure I get the second part of your question. Are you asking how to do do it with two forests? The answer is define two domains as you did it. If you asking what would be done in future then once we implement https://fedorahosted.org/sssd/ticket/2078 you would need just a single domain.
HTH
any detailed guidance will be highly appreciated (no documentation about this except for IPA which we don't use)
Thanks
