.SYNOPSIS
Emulates Azure AD Join or Azure AD Hybrid Join by registering the given device to Azure AD.
.DESCRIPTION
Emulates Azure AD Join or Azure AD Hybrid Join by registering the given device to Azure AD and generates a corresponding certificate.
You may use any name, type or OS version you like.
For Hybrid Join, the SID, tenant ID, and the certificate of the existing synced device must be provided - no access token needed.
The generated certificate can be used to create a Primary Refresh Token and P2P certificates. The certificate has no password.
.Parameter AccessToken
The access token used to join the device. To get MFA claim to PRT, the access token needs to be get using MFA.
If not given, will be prompted.
.Parameter DeviceName
The name of the device to be registered.
.Parameter DeviceType
The type of the device to be registered. Defaults to "Windows"
.Parameter OSVersion
The operating system version of the device to be registered. Defaults to "10.0.18363.0"
.Parameter Certificate
x509 device's user certificate.
.Parameter PfxFileName
File name of the .pfx device certificate.
.Parameter PfxPassword
The password of the .pfx device certificate.
.Parameter DomainControllerName
The fqdn of the domain controller from where the device information is "fetched". Defaults to "dc.aadinternals.com"
.Parameter DomainName
The domain name of the target Azure AD tenant. Defaults to "dc.aadinternals.com"
.Parameter TenantId
The tenant id of the target Azure AD tenant where the hybrid join device exists.
.Parameter SID
The SID of the device. Must be a valid SID and match the SID of the existing AAD device object.
.Parameter JoinType
The join type "Join" or "Register". Defaults to Join.
