The INTERDOMAIN_TRUST_ACCOUNT is a user-Account-Control Attribute Value that is a permit to trust an account for a system domain that trusts other domains.

When a Trust is established a Secure connection is set up later by the Netlogon service in the trust domain using the trust information that was stored by the user manager. After the trust is established, the RESOURCE PDC Emulator FSMO Role changes the trusted domain object password.

INTERDOMAIN_TRUST_ACCOUNTs credentials cannot be used in a normal session Microsoft Active Directory logon process and attempts will show the error "0xc0000198, Status_Nologon_Interdomain Trust_Account"
