strange vpn error

[Wei Weng <wengwei gmail com>]

Hi. I am using

ii  network-manager                   0.7.1~rc4.1.cf199a964-0ubuntu2
ii  network-manager-gnome             0.7.1~rc4.1-0ubuntu2
ii  network-manager-openvpn           0.7.1~rc4.1.20090323+bzr27-0ubunt
ii  network-manager-pptp              0.7.1~rc4.20090316+bzr23-0ubuntu3
ii  network-manager-vpnc              0.7.1~rc4.20090316+bzr21-0ubuntu2

I imported a VPNC profile file that works just fine using windows
cisco vpn client software. But I got error that says "The vpn
connection (xxxxx) failed because there were no valid VPN secrets". I
googled, but this error so far was only reported that happened on
ppptp client, I am using vpnc.

Can someone tell me what I am missing here???

Thanks
Wei

PS: The vpnc version I am using is

ii  vpnc                              0.5.3-1
