LookupAccountName
The LookupAccountName
function accepts the name of a system and an account as input. It retrieves a
security identifier (SID) for the account and the name of the domain on which
the account was found.
BOOL LookupAccountName(
|
LPCTSTR lpSystemName, |
// address of
string for system name |
|
LPCTSTR lpAccountName, |
// address of
string for account name |
|
PSID Sid, |

security identifier |
|
LPDWORD cbSid, |
// address of size
of security identifier |
|
LPTSTR ReferencedDomainName, |
// address of
string for referenced domain |
|
LPDWORD cbReferencedDomainName, |
// address of size
of domain string |
|
PSID_NAME_USE peUse |
// address of
SID-type indicator |

Parameters
lpSystemName
Points to a
null-terminated string specifying the system. This string can be the name of a
remote computer. If this string is NULL, the account name is looked up on the
local system.
lpAccountName
Points to a
null-terminated string specifying the account name.
Sid
Points to a
buffer receiving the SID
structure that corresponds to the account name pointed to by the lpAccountName
parameter.
cbSid
Pointer to a DWORD
variable. On input, this value specifies the size, in bytes, of the Sid
buffer. If the function fails because the buffer is too small, this variable
receives the required buffer size.
ReferencedDomainName
Points to a
buffer receiving the name of the domain where the account name is found.
cbReferencedDomainName
Pointer to a DWORD
variable. On input, this value specifies the size, in bytes (ANSI version) or
characters (Unicode version), of the ReferencedDomainName buffer. If the
function fails because the buffer is too small, this variable receives the
required buffer size, including the terminating null character.
peUse
Points to a SID_NAME_USE enumerated type indicating
the type of the account 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 LookupAccountName
function attempts to find a security identifier for the specified name by first
checking a list of well-known SIDs. If the name does not correspond to a
well-known SID, the function checks built-in and administratively defined local
accounts. Next, the function checks the primary domain. If the name is not
found there, trusted domains are checked.
