Hi,
I have configured PPTP VPN on Cisco 2821 router and PPTP works fine through Windows. But when i try to connect through Android default VPN it gives me following error. also please see attached error i get on Android mobile.
ppp128 PPP: Using AAA Unique Id = 9E
ppp128 PPP: Authorization NOT required
ppp128 PPP: Using vpn set call direction

Moreover, MS-CHAP-v2 does not authentication through local AAA default list. Does it only work with Radius?
Following is the configuration done on Cisco 2821 router.
aaa new-model

aaa authentication login default local
aaa authentication ppp default local
