 Here are some essential considerations when you're connecting:
 
-- `[email protected]` is the display name of the Microsoft Entra user.
+- `[email protected]` is the userPrincipalName of the Microsoft Entra user.
 - Be sure to use the exact way the Azure user is spelled. Microsoft Entra user and group names are case-sensitive.
 - If the name contains spaces, use a backslash (`\`) before each space to escape it.
   You can use the Azure CLI to get the signed in user and set the value for `PGUGSER` environment variable:
   ```bash
-  export PGUSER=$(az ad signed-in-user show --query "[displayName]" -o tsv | sed 's/ /\\ /g')
+  export PGUSER=$(az ad signed-in-user show --query "[userPrincipalName]" -o tsv | sed 's/ /\\ /g')
   ```
 - The access token's validity is 5 minutes to 60 minutes. You should get the access token before initiating the sign-in to Azure Database for PostgreSQL.
