blocks|key|1888146|text|我在另一个网站上找到了一个解决方案(见下文)。基本上，这个函数是转换器，使SID可见：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1888147|public+static+function+SIDtoString($ADsid)

I found a solution on another website (see below).
Basically this function is converter and makes SID visible:

<pre><code>public static function SIDtoString($ADsid)
{
 $sid = "S-";
 //$ADguid = $info[0]['objectguid'][0];
 $sidinhex = str_split(bin2hex($ADsid), 2);
 // Byte 0 = Revision Level
 $sid = $sid.hexdec($sidinhex[0])."-";
 // Byte 1-7 = 48 Bit Authority
 $sid = $sid.hexdec($sidinhex[6].$sidinhex[5].$sidinhex[4].$sidinhex[3].$sidinhex[2].$sidinhex[1]);
 // Byte 8 count of sub authorities - Get number of sub-authorities
 $subauths = hexdec($sidinhex[7]);
 //Loop through Sub Authorities
 for($i = 0; $i &lt; $subauths; $i++) {
 $start = 8 + (4 * $i);
 // X amount of 32Bit (4 Byte) Sub Authorities
 $sid = $sid."-".hexdec($sidinhex[$start+3].$sidinhex[$start+2].$sidinhex[$start+1].$sidinhex[$start]);
 }
 return $sid;
}
</code></pre>

blocks|key|2536104|text|作为另一个例子，这可以完全使用PHP的unpack函数来完成。objectSid二进制结构最好记录在这个MSDN文档上。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2536105|修订(1字节)：一个8位无符号整数，指定SID的修订级别。此值必须设置为0x01。
SubAuthorityCount+(1字节)：指定SubAuthority数组中元素数的8位无符号整数。允许的最大元素数为15个。
IdentifierAuthority+(6字节)：指示创建SID的权限的SID_IDENTIFIER_AUTHORITY结构。它描述了创建SID的实体。标识符授权值{0,0,0,0,0,5}表示由NT+SID授权机构创建的SID。
SubAuthority+(变量)：由32位无符号整数组成的可变长度数组，唯一标识相对于IdentifierAuthority的主体。其长度由SubAuthorityCount决定。|blockquote|style|BOLD|2536106|/**

As an alternative example, this can be done completely using PHP's unpack function. The objectSid binary structure is best documented on <a href="https://msdn.microsoft.com/en-us/library/gg465313.aspx" rel="nofollow noreferrer">this MSDN doc</a>:

<blockquote>
 Revision (1 byte): An 8-bit unsigned integer that specifies the
 revision level of the SID. This value MUST be set to 0x01.
 
 SubAuthorityCount (1 byte): An 8-bit unsigned integer that specifies
 the number of elements in the SubAuthority array. The maximum number
 of elements allowed is 15.
 
 IdentifierAuthority (6 bytes): A SID_IDENTIFIER_AUTHORITY structure
 that indicates the authority under which the SID was created. It
 describes the entity that created the SID. The Identifier Authority
 value {0,0,0,0,0,5} denotes SIDs created by the NT SID authority.
 
 SubAuthority (variable): A variable length array of unsigned 32-bit
 integers that uniquely identifies a principal relative to the
 IdentifierAuthority. Its length is determined by SubAuthorityCount.
</blockquote>

<pre><code>/**
 * Decode the binary SID into its readable form.
 *
 * @param string $value
 * @return string
 */
function decodeSID($value)
{
 # revision - 8bit unsigned int (C1)
 # count - 8bit unsigned int (C1)
 # 2 null bytes
 # ID - 32bit unsigned long, big-endian order
 $sid = @unpack('C1rev/C1count/x2/N1id', $value);
 $subAuthorities = [];

 if (!isset($sid['id']) || !isset($sid['rev'])) {
 throw new \UnexpectedValueException(
 'The revision level or identifier authority was not found when decoding the SID.'
 );
 }

 $revisionLevel = $sid['rev'];
 $identifierAuthority = $sid['id'];
 $subs = isset($sid['count']) ? $sid['count'] : 0;

 // The sub-authorities depend on the count, so only get as many as the count, regardless of data beyond it
 for ($i = 0; $i &lt; $subs; $i++) {
 # Each sub-auth is a 32bit unsigned long, little-endian order
 $subAuthorities[] = unpack('V1sub', hex2bin(substr(bin2hex($value), 16 + ($i * 8), 8)))['sub'];
 }

 # Tack on the 'S-' and glue it all together...
 return 'S-'.$revisionLevel.'-'.$identifierAuthority.implode(
 preg_filter('/^/', '-', $subAuthorities)
 );
}

blocks|key|2536114|text|这在64位系统上有效，我认为它更简洁。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2536115|function+bin_to_str_sid($binsid)+{

This works on 64bit systems and I think is more succinct.

 $ssid = sprintf('S-%u-%d', $parts['rev'], ($parts['idhigh']&lt;&lt;32) + $parts['idlow']);

Is old post but I do some combination what I find useful and this function is the ultimate function for binary to SID translations:

<pre><code>// Binary to SID
function bin_to_str_sid($binary_sid) {

 $sid = NULL;
 /* 64bt PHP */
 if(strlen(decbin(~0)) == 64)
 {
 // Get revision, indentifier, authority 
 $parts = unpack('Crev/x/nidhigh/Nidlow', $binary_sid);
 // Set revision, indentifier, authority 
 $sid = sprintf('S-%u-%d', $parts['rev'], ($parts['idhigh']&lt;&lt;32) + $parts['idlow']);
 // Translate domain
 $parts = unpack('x8/V*', $binary_sid);
 // Append if parts exists
 if ($parts) $sid .= '-';
 // Join all
 $sid.= join('-', $parts);
 }
 /* 32bit PHP */
 else
 { 
 $sid = 'S-';
 $sidinhex = str_split(bin2hex($binary_sid), 2);
 // Byte 0 = Revision Level
 $sid = $sid.hexdec($sidinhex[0]).'-';
 // Byte 1-7 = 48 Bit Authority
 $sid = $sid.hexdec($sidinhex[6].$sidinhex[5].$sidinhex[4].$sidinhex[3].$sidinhex[2].$sidinhex[1]);
 // Byte 8 count of sub authorities - Get number of sub-authorities
 $subauths = hexdec($sidinhex[7]);
 //Loop through Sub Authorities
 for($i = 0; $i &lt; $subauths; $i++) {
 $start = 8 + (4 * $i);
 // X amount of 32Bit (4 Byte) Sub Authorities
 $sid = $sid.'-'.hexdec($sidinhex[$start+3].$sidinhex[$start+2].$sidinhex[$start+1].$sidinhex[$start]);
 }
 }
 return $sid;
}
</code></pre>

Now you can chillout and use this function in any PHP version.

I don't know how to get users unique identifier (SID) in AD. Code fragment:

<pre><code>... 
$filter="(&amp;(samaccountname=".$this-&gt;username.")(memberOf:1.2.840.113556.1.4.1941:=CN=GROUP_NAME,OU=Security,DC=something,DC=something))";
 $attribute = array("cn","objectsid","description", "group", "member", "samaccountname");
 $sr=ldap_search($this-&gt;conn_ldap, $this-&gt;ldap_dn, $filter, $attribute);

 if ($sr) 
 {

 $this-&gt;info = ldap_get_entries($this-&gt;conn_ldap, $sr);
 if ($this-&gt;info["count"] == 1){

 ldap_close($this-&gt;conn_ldap);
 return true;
 }
 ... 
</code></pre>

i can pull information with:

<pre><code>echo $this-&gt;info[0]["cn"][0];
</code></pre>

or

<pre><code>echo $this-&gt;info[0]["objectsid"][0];
</code></pre>

In first output i can see users name in secound something like <code>0�@�d^�WL7�U</code>
I believe sid should be like <code>S-......</code>?
