MC67 Android EAP-TLS PIN Requirement

Anyone aware if the credentials can be cached once the PIN is entered?  Target is MC67 Android KK.  Device is locked down and user will not have access to enter the PIN.  Customer will be using; LAN, WiFi and Cellular.  I have to confirm the LAN to WiFi transition; however, when transitioning from cellular to WiFi, re-authentication on the WiFi network is forcing PIN re-entry.

 

All feedback is appreciated.

Don
