Grafana SSO login issue

Hello Team,
We are facing issue while configuring the Grafana SSO .

Currently we had configured it with using Azure AD .

All the active directory level configuration and user are already added but it is authenticated everyone with SSO with defined domain who has that email id .

I need to know is there is any Grafana level configuration we need to add in value.yaml

We had tried to check Azure level and grafana level configuration all looks fine . Below are the details

we have also tried with adding group id created in Azure AD but still it is authenticating all user who has that defined domain id
Below is configuration file added in prometheus Helm charts

name = Azure AD
enabled = true
allow_sign_up = true
auto_login = false
client_id = APPLICATION_ID
client_secret = CLIENT_SECRET
scopes = openid email profile
auth_url = 
token_url = 
allowed_domains = lntinfotech .com 
allowed_groups = 

Kindly have a look  and suggest
