Setup Forest Trust

we have root empty domain called company.local , child domain our users located corp.company.local

there 2-way transitive parent-child trust between company.local , corp.company.local

we have application running in aws runs own ad forest called app.aws.local

we need setup one-way trust users in corp.company.local can authenticate on app.aws.local servers

i have tried create trust between corp.company.local , app.aws.local fails time, if try create trust between company.local (the root domain) , app.aws.local succeeds can browse resources in root domain not child.

what missing , should trust direction? thinking making one-way incoming trust company.local , one-way outgoing trust app.aws.local

hi,

you need outgoing trust aws.local to company.local able authenticate against aws app.
