# Connecting to an Azure AD Stamp

## HOST VM OF THE STAMP TO BE CONFIGURED

On **AzS Development Kits**, sign in to the physical host. 

On **multi-node integrated systems**, the host must be a system that can access admin end point.

1. Place the RegisterBillingWithIdentitySystem.ps1 file in a temp folder.  This file can be found in the install folder of Host VM where Billing resource provider was installed: c:\CloudAssert\BillingRP\BillingApp\\
2. Open a new elevated (administrative) PowerShell console and change to the above directory. Use a new window to avoid problems that might arise from incorrect PowerShell modules that are already loaded on the system
3. Run the RegisterBillingWithIdentitySystem.ps1 script with appropriate parameters

```
.\RegisterBillingWithIdentitySystem.ps1 -ServiceAdminUser '' -AzureStackAdminResourceManagerEndpoint '' -AzureDirectoryTenantId '' -AzureEnvironment 'AzureCloud' -IdentitySystemType 'AzureAD' -adminSubscriptionId ''

Eg:
.\RegisterBillingWithIdentitySystem.ps1 -ServiceAdminUser 'msmtest@cloudassertrp.contoso.com' -AzureStackAdminResourceManagerEndpoint 'https://adminmanagement.local.contoso.com/' -AzureDirectoryTenantId 'eef3d6b3-cf97-42c1-9cc5-f68905cdd1a6' -AzureEnvironment 'AzureCloud' -IdentitySystemType 'AzureAD' -adminSubscriptionId 'a7f2bc5b-2287-4a8b-b256-dcb14dd06878'
```
