NTP authentication issue

I have NTP set up between two routers with the following configuration,
using a md5 password of "cisco". R1 is the master. Everything
synchronizes and is happy. However, I am purposely trying to break it,
by changing the password at R1 to "wellfleet" (all the old guys <like
me> will appreciate that). Unfortunately, R5 still synchronizes (and it
shouldn't). Am I missing something? Here are the configs.....

!
hostname R1
!
interface Ethernet0
 ip address 192.168.150.100 255.255.255.0
!
interface Serial0
 ip address 10.10.10.1 255.255.255.0
 ip pim nbma-mode
 ip pim sparse-mode
 encapsulation frame-relay
 no ip mroute-cache
 no fair-queue
 frame-relay map ip 10.10.10.1 105
 frame-relay map ip 10.10.10.5 105 broadcast
 frame-relay map ip 10.10.10.6 106 broadcast
 no frame-relay inverse-arp
!
ntp authentication-key 1 md5 051C03032D4A420C1C11 7
ntp trusted-key 1
ntp master 3
!

!
hostname R5
!
interface Serial0
 ip address 10.10.10.5 255.255.255.0

 frame-relay map ip 10.10.10.6 501
 no frame-relay inverse-arp
!
