Hi Randy, You will need authentication for the BRI interface for OSPF area 0, an dyou definatley only need the deman circuit to be on one side, not both. What errors are you getting ? Presumaly since you are asking about passwods, I assume the BRI interfaces are not connecting? Have you configured username and password on the called router for the calling router? Do a debug ppp authentication,. and see what the output of that says.
Also with redistributing RIP and OSPF, you need to make your BRI interface is exlcuded from RIP and EIGRP, as if the interface comes up / goes down it would trigger another state change which would be redistributed into OSPF and thus, keep the circuit up all the time !
