SecPkgCredentials_KdcNetworkSettingsW structure (ntifs.h)

  • Article

The SecPkgCredentials_KdcNetworkSettingsW structure is used to configure network settings for Kerberos Key Distribution Center (KDC) communications in secure environments. It is typically used in scenarios where specific network configurations are required for secure communication with KDCs.

Syntax

typedef struct _SecPkgCredentials_KdcNetworkSettingsW {
  ULONG  Version;
  ULONG  Flags;
  USHORT ProxyServerOffset;
  USHORT ProxyServerLength;
  USHORT ClientTlsCredOffset;
  USHORT ClientTlsCredLength;
  ULONG  DcDiscoveryFlags;
} SecPkgCredentials_KdcNetworkSettingsW, *PSecPkgCredentials_KdcNetworkSettingsW;
