How to configure line breaking on ADmanagerplus log?

[wliu_ondeck]

I am working on ingesting ADmanagerplus logs. I am having difficulty linebreaking the following log which represents one event. How can I successfully configure this so splunk recognizes this as one event and not one event per line.
