I want to login via Active Directory Users into IDM User Application. For this I followed the below URL

After all configuration when I hit the User Application URL (http://dev.demo.local:8180/IDMProv) it will ask for the Active Directory User credentials and after entered the credentials I will redirect to the User Application login page and In the User Application logs I am getting the below Error
