!!! Overview A value of the [{$pagename}] [LDAPSyntaxes] is a sequence of zero, one, or more arbitrary octets. An octet is a [byte], and an [{$pagename}] is simply zero or more [bytes] strung together. !! [{$pagename}] and [LDAP] [{$pagename}] has an [OID] of [1.3.6.1.4.1.1466.115.121.1.40] or [Microsoft Active Directory] [2.5.5.10] [{$pagename}] [bytes] can represent [Plaintext] in [LDAP], which is usually the bytes that comprise the [UTF-8] representation of that text, or they can just make up some arbitrary blob of [binary] [data]. [LDAP] uses octet strings all over the place, including for DNs, attribute names and values, diagnostic messages, and to hold the encoded values of controls, extended requests and responses, and [SASL] [credentials]. In [LDAP], [{$pagename}] are always primitive where [BER] allows for the possibility of constructed octet strings, but [RFC 4511] section 5.1 forbids constructed octet strings use in [LDAP]. The universal BER type for an octet string element is 0x04, and the [hexadecimal] [bytes] that correspond to the [UTF-8] [Encoding] text string “Hello!” are: {{{ 48 65 6c 6c 6f 21}}} , so the encoding for a universal octet string element meant to hold the text string “Hello!” is: {{{ 04 06 48 65 6c 6c 6f 21 }}} The LDAP-specific [encoding] of a value of this syntax is the unconverted sequence of octets, which conforms to the following [ABNF]: {{{ OctetString = *OCTET }}} The <OCTET> rule is defined in [RFC 4512]. Values of this syntax are not generally human-readable. The LDAP definition for the Octet String syntax is: {{{ ( 1.3.6.1.4.1.1466.115.121.1.40 DESC 'Octet String' ) }}} [{$pagename}] syntax corresponds to the OCTET STRING [ASN.1] type from [ASN.1]. !!
