The following contains a quick reference for how to extend the OpenID Connect ID Token that we created in this blog post with additional attributes.
Start by modifying the manifest of the app registration, changing “acceptMappedClaims” to true.
Second, add a new Azure AD Policy with the actual claims mapping using PowerShell cmdlet New-AzureADPolicy:
Connect-AzureAD
$servicePrincipal = Get-AzureADServicePrincipal -SearchString "Our Demo App"
$definition = @(
'{"ClaimsMappingPolicy":{"Version":1,"IncludeBasicClaimSet":"true", "ClaimsSchema": [
{"Source":"user","ID":"jobtitle","JwtClaimType":"jobtitle"},
{"Source":"user","ID":"department","JwtClaimType":"department"},
{"Source":"user","ID":"onpremisessamaccountname","JwtClaimType":"uid"},
{"Source":"user","ID":"mailnickname","JwtClaimType":"mailnickname"}
]}}'
)
$Policy = New-AzureADPolicy -Definition $definition -DisplayName "DemoApplicationClaimsMappingPolicy" -Type "ClaimsMappingPolicy"
<#
Or if you need to update the policy:
Set-AzureADPolicy -Id $Policy.Id -Definition $definition
#>
Add-AzureADServicePrincipalPolicy -Id $servicePrincipal.ObjectId -RefObjectId $Policy.Id
Signing in after this, requesting an ID token (see this blog post for these details), jwt.ms helps us see that we indeed get our additional attributes as claims in the ID Token:
Good luck 🙂
Good Workaround! 
I see you are setting this claim
“`
{“Source”:”user”,”ID”:”onpremisessamaccountname”,”JwtClaimType”:”uid”},
“`
But i dont see it in the token.
What if you set these properties in that token?
“`
“SamlClaimType”: “samaccountname”,
“JwtClaimType”: “samAccountName”
“`
