I am getting an error “The Server not operational”

This error most commonly occurs when the server used in direct server binding cannot be contacted. It can be caused by:

• An incorrect server name in WhereToBind (e.g LDAP://incorrect-server-name.test.com/OU=Test,DC=test,DC=com)
• Insufficient permissions to connect to the server (try using different credentials for the host instance that handles ActiveADAPTER)
