Properties of a home realm discovery policy definition

The following object shows the properties that form the JSON object for a token lifetime policy definition. This JSON object must be converted to a string with quotations escaped to be inserted into the definition property as shown in the following example.

"definition": [
    "{
        \"HomeRealmDiscoveryPolicy\": {
          \"AccelerateToFederatedDomain\":true,
          \"AllowCloudPasswordValidation\": false,
          \"PreferredDomain\":\"federated.example.edu\",
          \"AlternateIdLogin\":{
            \"Enabled\":true
          }
        }
      }"
  ]
Property Type Description
AccelerateToFederatedDomain Boolean Set to true for autoacceleration (bypass home realm discovery). If true and there's only one verified and federated domain in the tenant, then users are taken straight to the federated identity provider (such as ADFS) for sign in. If true and there's more than one verified domain in the tenant, PreferredDomain must be specified. Optional.
AllowCloudPasswordValidation Boolean Set to true to allow an application to authenticate a federated user by presenting username/password credentials directly to the Microsoft Entra token endpoint. Only works if Password Hash Sync is enabled. Optional.
AlternateIdLogin Json Set to {\"Enabled\": true} to allow Microsoft Entra sign-in using email as an alternate login ID. Only works when IsOrganizationDefault is set to true. Optional.
PreferredDomain String Specifies a domain to accelerate sign-in to. It can be omitted if the tenant has only one federated domain. If it's omitted, and there's more than one verified federated domain, this policy has no effect. Required if AccelerateToFederatedDomain is true.

Relationships

Relationship Type Description
appliesTo directoryObject collection The directoryObject collection that this policy has been applied to. Read-only.
