vpn error message, MPPE required but not available



my setup:
non production machine running mac os x 10.5 server
open directory master
dns server running on open directory master
static ip address
forward and reverse dns records set up on dns for the open directory master.
firewall off
service ACL set to everyone for all services


when i try to connect to a pptp vpn from a 10.5 client to the 10.5 server above (from the LAN, ie, no routers involved) i get the following error message:

Thu Nov 1 02:12:39 2007 : CHAP peer authentication succeeded for admin
Thu Nov 1 02:12:39 2007 : DSAccessControl plugin: User 'admin' authorized for access
Thu Nov 1 02:12:39 2007 : MPPE required, but keys are not available. Possible plugin problem?
Thu Nov 1 02:12:39 2007 : sent [LCP TermReq id=0x2 "MPPE required but not available"]



when i then run the following commands:

$ dscl /LDAPv3/127.0.0.1 -list /Users

admin
marknassy
root


# vpnaddkeyagentuser /LDAPv3/127.0.0.1 Enter admin name for node /LDAPv3/127.0.0.1:admin Password: $ dscl /LDAPv3/127.0.0.1 -list /User

admin
marknassy
root

if i try to connect via pptp vpn i get the same error message listed above. ipsec vpn connection attempt gives the same error message. does anyone have any suggestions for further troubleshooting?
