Narrative:

Inbound to gso on the henby 1 arrival, a maximum authority/authorized altitude is published at FL210. A few weeks ago, I inquired about it to center because it appeared we would not be able to comply with the maximum authority/authorized altitude. The controller answered it did not apply because we were using GPS navigation. This week, during this reported event, the event controller asked the reason we were not increasing the rate of descent in order to comply with the maximum authority/authorized altitude. He had cleared us to FL200. We were also using GPS navigation. Callback conversation with reporter revealed the following information: the reporter's concern was different information given by different controllers. Once hearing the reason the reporter accepted the answer. The reporter will request relief from the maximum authority/authorized altitude the next time he flies the approach.
