Hi All, I would like to add app roles to my service principal in Azure AD.
[CmdletBinding()]
Param
(
[Parameter(Mandatory = $true)][string]$AppName,
[Parameter(Mandatory = $true)][string]$token,
[Parameter(Mandatory = $true)][string[]] $AllowedMemberTypes
)
try {
#Connect-AzureAD
Install-Module -Name AzureAD -Scope CurrentUser -Force
$currentAzureContext = Get-AzContext
$tenantId = $currentAzureContext.Tenant.Id
$accountId = $currentAzureContext.Account.Id
Connect-AzureAD -AadAccessToken $token -AccountId $accountId -TenantId $tenantId
# Create an application role of given name and description
$Id = [Guid]::NewGuid().ToString()
# Create new AppRole object
$newAppRole = [Microsoft.Open.AzureAD.Model.AppRole]::new()
$newAppRole.AllowedMemberTypes = New-Object System.Collections.Generic.List[string]
$newAppRole.AllowedMemberTypes.Add("User")
$newAppRole.DisplayName = "User"
$newAppRole.Description = "User Role"
$newAppRole.Value = "User"
$newAppRole.Id = $Id
$newAppRole.IsEnabled = $true
# Add new AppRole and apply changes to Application object
$App = Get-AzureADServicePrincipal -Filter "displayName eq '$AppName'"
$appRoles = $App.AppRoles | Where-Object { $_.DisplayName -eq $RoleToAssign }
echo $appRoles
$SPNObjectId=(Get-AzADServicePrincipal -DisplayNameBeginsWith $AppName).Id
echo $SPNObjectId
$appRoles += $newAppRole
echo $appRoles
Set-AzureADApplication -ObjectId $SPNObjectId -AppRoles $appRoles
}
