Hi @Venkatesanj4 To debug this error step by step, we would need a bit more information about your configuration, for example: –Are you using TLS? –Is this a new server or installation? –how are you logging in, and what type of credential is being used? –Is this system in the same Windows domain as the domain controller? –What steps have you already attempted to try to solve the issue? I have found that some others have reported the solution that worked for them, such as: a.) If you are registering a user, then the same user needs to be configured under IQService username and password in Sailpoint AD configuration page. b.) I de-registered and registered the user to the IQService, and it started to work fine . c.) Have IQService server to be a member server of the AD domain.
