2.45 Attribute objectSid

This attribute specifies a binary value that specifies the security identifier (SID) of a security principal object. The SID is a unique value used to identify security principal objects. For more information on the SID data type, refer to [MS-DTYP] section 2.4.2. SID usage is also discussed in [MS-ADTS], in particular in section

Because this is an attribute of String(SID) syntax, an application writing to this attribute via the LDAP protocol can specify a value for this attribute as a valid SDDL SID string, as specified in [MS-ADTS] section The directory service will convert that value to its binary value equivalent.
