Out of box Active Directory orchestration activity such as 'Add User to Group' that use a credential tag may result in Success even if the activity actually fails due to missing credential (for the tag used).

When a credential with the credential tag that is used in the activity is not found, credentials_debug does not return errors in the probe input record. This causes 'errorMessages' in the raw output of the response received to be null. The post processing script of the activity looks at the response received and if there is a value in 'errorMessages' of the raw output, the activity is set to 'failure', otherwise the activity result is set to 'success'.

An access denied message in the MID server agent log, similar to the one below for '' is an indication of the issue.
