NetworkManager-pptp, -vpnc problem

Hi

I have problem connecting to Windows 2003 VPN server from OpenSUSE 11.1 (gnome) using NetworkManager (vpnc, pptp plugin).
I can’t find EAP authentication option in VPN configuration.
I need to refuse EAP authentication in order to connect the vpn server.

I manually add following lines to ~/.gconf/system/networking/connections/1/vpn/%gconf.xml:
<entry name=“refuse-eap” mtime=“1244074989” type=“string”>
<stringvalue>yes</stringvalue>
</entry>
But no luck.

Does anybody know how to solve this problem?

FYI: I do not have problem connecting the VPN server using kvpnc.

Thanks!
