# Trusts

## General

* Relationship between two domains or forest
* Trusted Domain Objects (TDOs) represent trust relationship in a domain
* Types of trusts
  * One-way: users in trusted domain can access resources in the trusting domain
  * Two-way trust: users of both domains can access resources in the other domain
  * Transitive: If A and B trust each other and B and C trust each other, A and C also trust each other (default between domains in same forest)
  * Non-transitive: cannot be extended to other domains in the forest (default between two domains in different forests)
  * Automatic trust: created automatically when creating new subdomain (parent-child, tree-root)
  * Shortcut trusts: used to reduce access time in complex trust scenarios
  * External trusts: between two domains in different forests when forests do not have a turst relationships
  * Forest trusts: between forest root domains
