You need to put the "ppp chap hostname <name>" command on both dialer
interfaces, then you need to define the ppp chap hostname and password in
the global command, "username <name> password <password>". If you do not
want to use the username, get rid of the your "ppp chap password" command in
the dialer interface. You are also complicating the issue by using dialer
interfaces, the "dialer string" command should be used on it, not the
"dialer map". Try to do the same setup with just the bri interfaces. Did
you try a "debug ppp authentication" to see if the authentication is
successful?
