run the following PowerShell script to assign several required permissions to the App Service managed identity. Required permissions follow the least-privilege principle and include the following:
Graph API / Permissions name | Access Granted by Permissions | Used By |
AuditLog.Read.All | Read audit log data | App Service Managed Identity |
Group.Read.All | Read group data | App Service Managed Identity |
GroupMember.ReadWrite.All | Read and write group memberships | App Service Managed Identity |
User.Read.All | Read user profile | App Service Managed Identity |
Reports.Read.All | Read report data | App Service Managed Identity |
Organization.Read.All | Read organization information | App Service Managed Identity |
The above permissions have been added to the script's PermissionsToAdd parameter, shown below. In addition to adding the permissions, you need to enter values for these parameters:
tenantID — Your Tenant ID
appServiceObjectID — Object ID of the SCIM App Service
| Tip |

When running the script, be sure to authenticate to Azure as a user with adequate permissions to execute it in Azure AD (owner at the tenant level). |
