AuthzInitializeContextFromAuthzContext function

The AuthzInitializeContextFromAuthzContext function creates a new client context based on an existing client context.

Starting with Windows Server 2012 and Windows 8, this function also duplicates device groups, user claims, and device claims.

Syntax

BOOL WINAPI AuthzInitializeContextFromAuthzContext(
  _In_     DWORD                        flags,
  _In_     AUTHZ_CLIENT_CONTEXT_HANDLE  hAuthzClientContext,
  _In_opt_ PLARGE_INTEGER               pExpirationTime,
  _In_     LUID                         Identifier,
  _In_     PVOID                        DynamicGroupArgs,
  _Out_    PAUTHZ_CLIENT_CONTEXT_HANDLE phNewAuthzClientContext
);

Parameters

flags [in]

Reserved for future use.

hAuthzClientContext [in]

The handle to an existing client context.

pExpirationTime [in, optional]

Sets the time limit for how long the returned context structure is valid. If no value is passed, then the token never expires. Expiration time is not currently enforced.

Identifier [in]

The specific identifier for the resource manager.

DynamicGroupArgs [in]

A pointer to parameters to be passed to the callback function that computes dynamic groups. If the value is NULL, then the callback function is not called.

phNewAuthzClientContext [out]

A pointer to the duplicated AUTHZ_CLIENT_CONTEXT_HANDLE handle. When you have finished using the handle, release it by calling the AuthzFreeContext function.

Return value

If the function succeeds, it returns TRUE.

If the function fails, it returns FALSE. To get extended error information, call GetLastError.

Remarks

This function calls the AuthzComputeGroupsCallback callback function to add security identifiers to the newly created context.
