Hi Shamprasad,

 

The error message suggests that you didn't authorize the user to the specific application. If you go to Azure Active Directory => Enterprise Applications => "Application Name".

Is the user visible under Users and Groups there?

 

If that's not the problem, do you see any additional error messages in the eventlog on the Application Proxy?

 

Best regards,

Ruud Gijsbers

Yes the users is available in the access list. I have not checked the AD logs, please let me know how to check them as I am not a AD expert. I can share them with you

    If you logon to the server where the Azure AD Application Proxy is installed, you can examine  the Eventlogs with Eventviewer: Start => CMD => eventvwr.

    Under Application and Services Logs => Microsoft => AadApplicationProxy => Connector => Admin you can see the events regarding your application proxy. Search for errors or warnings regarding your application..

     

    If there aren't any logs generated, that means that there's something wrong with the configuration of the specific app in Azure AD and  that the traffic never lands on the Azure AD Application Proxy.
