The LsaRegisterLogonProcess function establishes a connection to the LSA server and verifies that the caller is a logon application.
Pointer to an LSA_STRING structure identifying the logon application. This should be a printable name suitable for display to administrators. For example, the Windows logon application might use the name "User32LogonProcess". This name is used by the LSA during auditing. LsaRegisterLogonProcess does not check whether the name is already in use.
This string must not exceed 127 bytes.
Pointer that receives a handle used in future authentication function calls.
The value returned is not meaningful and should be ignored.
If the function succeeds, the return value is STATUS_SUCCESS.
If the function fails, the return value is an NTSTATUS code. The following are possible error codes.
| Return code | Description |
|---|---|
|
The caller does not have the SeTcbPrivilege privilege, which is required to call this function.
You can set this privilege by calling LsaAddAccountRights. |
|
The specified logon process name exceeds 127 bytes. |
For more information, see LSA Policy Function Return Values.
The LsaNtStatusToWinError function converts an NTSTATUS code to a Windows error code.
This function must be called before a logon process may use any other logon authentication functions provided by the LSA.
The LsaRegisterLogonProcess function verifies that the application making the function call is a logon process by checking that it has the SeTcbPrivilege privilege set. It also opens the application's process for PROCESS_DUP_HANDLE access in anticipation of future LSA authentication calls. For more information, see DuplicateHandle.
When you have finished using the connection to the LSA server, delete the caller's logon application context and close the connection by calling the LsaDeregisterLogonProcess function.
