Kids in colleges and universities who r Special aka Special Needs/disabilities

So I have a daughter who is in any town USA getting a degree in XYZ and is a Sophomore. My conflict is that her school has a disabilities center, has documents proving her disabilities yet she is catching flack from 1 professor and kids on a group project. I’m wondering if other parents/caregivers are having this issue and what actions they take. We did our due diligence, sought guidance from HS mentors and yet they said what we wanted to hear and were looking for. Mutual respect will be appreciated.
