OpenThreadToken info  Overview  Group

The OpenThreadToken function opens the access token associated with a thread.

BOOL OpenThreadToken(

    HANDLE ThreadHandle,

// handle to thread

    DWORD DesiredAccess,

// access to process

    BOOL OpenAsSelf,

// flag for process or thread security

    PHANDLE TokenHandle 

// pointer to handle to open access token

   );

Parameters

ThreadHandle
Identifies the thread whose access token is opened.
DesiredAccess
Specifies an access mask that specifies the requested types of access to the access token. These requested access types are reconciled against the tokenís discretionary access-control list (ACL) to determine which accesses are granted or denied. The following access rights have been defined for access tokens.

Value

Meaning

TOKEN_ADJUST_DEFAULT

Required to change the default ACL, primary group, or owner of an access token.

TOKEN_ADJUST_GROUPS

Required to change the groups specified in an access token.

TOKEN_ADJUST_PRIVILEGES

Required to change the privileges specified in an access token.

TOKEN_ALL_ACCESS

Combines the STANDARD_RIGHTS_REQUIRED standard access rights and all individual access rights for tokens.

TOKEN_ASSIGN_PRIMARY

Required to attach a primary token to a process in addition to the SE_CREATE_TOKEN_NAME privilege.

TOKEN_DUPLICATE

Required to duplicate an access token.

TOKEN_EXECUTE

Combines the STANDARD_RIGHTS_EXECUTE standard access rights and the TOKEN_IMPERSONATE access right.

TOKEN_IMPERSONATE

Required to attach an impersonation access token to a process.

TOKEN_QUERY

Required to query the contents of an access token.

TOKEN_QUERY_SOURCE

Required to query the source of an access token.

TOKEN_READ

Combines the STANDARD_RIGHTS_READ standard access rights and the TOKEN_QUERY access right.

TOKEN_WRITE

Combines the STANDARD_RIGHTS_WRITE standard access rights and the TOKEN_ADJUST_PRIVILEGES, TOKEN_ADJUST_GROUPS, and TOKEN_ADJUST_DEFAULT access rights.

OpenAsSelf
Specifies a flag indicating whether the access check is to be made against the security context of the thread calling the OpenThreadToken function or against the security context of the process for the calling thread.

If this parameter is FALSE, the access check is performed using the security context for the calling thread. If the thread is impersonating a client, this security context can be that of a client process. If this parameter is TRUE, the access check is made using the security context of the process for the calling thread.

TokenHandle
Points to a handle identifying the newly opened access token when the function returns.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The OpenAsSelf parameter allows a server process to open the access token for a client process when the client process has specified the SecurityIdentification impersonation level for the SECURITY_IMPERSONATION_LEVEL enumerated type. Without this parameter, the calling process is not be able to open the clientís access token using the clientís security context, because it is impossible to open executive-level objects using the SecurityIdentification impersonation level.
