Did the Buddha work with teachers from other spiritual traditions?

Within the Pali canon the Buddha often vigorously debates with Brahmin priests. However in the Buddha's time there were a lot of other spiritual traditions too. Did the Buddha have more cordial relationships with teachers of other faiths too? Are there examples of him working together with spiritual teachers of other traditions? I'm specifically asking about his teaching after he became enlightened. I know he studied with several teachers before that point.
