Traffic is matching both the ACLs. Authentication is taking place using telnet, but not able to ping after being authenticated. Without all these configs pings are working fine. So no issues with routing/icmp inspection or anything of that sort.
Can you see if the pings are getting to R2. On R2, do a "debug ip icmp" just to make sure that icmp echos aren't making it. It is very curious that it worked before, but not after adding the UAUTH. The ACL is more of a trigger than anything, I don't know why it would have an issue after the user is authenticated.
