When running iOS 11 and pushing a Wi-Fi profile with 'WPA2 Enterprise' PEAP security type, devices receiving the profile will not see the password field and is unable to connect to the Wi-Fi.
The current workaround is to have devices connect manually to the Wi-Fi. The password field should appear when connecting manually.
