LPRASENTRY建立链接，如果支持PAP

[xjb2001]

lpRasEntry->dwfOptions |= RASEO_RemoteDefaultGateway;
lpRasEntry->dwfOptions |= RASEO_ShowDialingProgress;//RASEO_ShowDialingProgress ;
lpRasEntry->dwfOptions |= RASEO_PreviewUserPw;
lpRasEntry->dwfOptions |= RASEO_ModemLights;

lpRasEntry->dwfOptions |= RASEO_RequirePAP;

lpRasEntry->dwfOptions |= RASEO_RequireEncryptedPw;

lpRasEntry->dwEncryptionType = ET_Optional;

这么建立的链接，是支持PAP和MS-CHAP的，但是 PAP 不支持

如何把PAP这个选项勾上？
