PPP Authentication between 2 Routers

Hello all,

I have just configured in a Point to Point Link, PPP Authentication
between 2 Routers, say R4 (se0/1) === (se0/1) R5.

Defining R4 as the Authenticator in this scenario, should make R5 look
in his local database, but it seems not to be doing this at all--

Im missing something here??

Thanks
Victor.
