Overview #

DN Syntax is a LDAPSyntaxes for Distinguished Name (DN) of an LDAP Entry as defined in RFC 4512.

The OID for DN Syntax is 1.3.6.1.4.1.1466.115.121.1.12

The LDAP-specific encoding of a value of this DN Syntax is defined by the distinguishedName rule from the String Representation of Distinguished Names (RFC 4514).

Examples (from RFC 4514):

  • UID=jsmith,DC=example,DC=net
  • OU=Sales+CN=J. Smith,DC=example,DC=net
  • CN=John Smith\, III,DC=example,DC=net
  • CN=Before\0dAfter,DC=example,DC=net
  • 1.3.6.1.4.1.1466.0=#04024869,DC=example,DC=com
  • CN=Lu\C4\8Di\C4\87

Distinguished Name Case Sensitivity is not consistent across LDAP Server Implementations

The DN Syntax corresponds to the DistinguishedName ASN.1 type from X.501. Note that a BER encoded distinguished name (as used by X.500) re-encoded into the LDAP-specific encoding is not necessarily reversible to the original BER encoding since the chosen string type in any DirectoryString components of the Distinguished Name is not indicated in the LDAP-specific encoding of the distinguished name. (see Section 3.3.6 of RFC 4517).
