Attribute:  houseIdentifier 

Syntax: Directory String

ID : 1.3.6.1.4.1.1466.115.121.1.15
A string in this syntax is encoded in the UTF-8 form of ISO 10646 (a superset of Unicode). Servers and clients MUST be prepared to receive encodings of arbitrary Unicode characters, including characters not presently assigned to any character set.

For characters in the PrintableString form, the value is encoded as the string value itself.

If it is of the TeletexString form, then the characters are transliterated to their equivalents in UniversalString, and encoded in UTF-8 [9].

If it is of the UniversalString or BMPString forms [10], UTF-8 is used to encode them.

Note: the form of DirectoryString is not indicated in protocol unless the attribute value is carried in binary. Servers which convert to DAP MUST choose an appropriate form. Servers MUST NOT reject values merely because they contain legal Unicode characters outside of the range of printable ASCII.

Example:

      This is a string of DirectoryString containing #!%#@

Equality Matching: caseIgnoreMatch

Description:

Servers SHOULD be capable of performing the following matching rules.

For all these rules, the assertion syntax is the same as the value syntax.

When performing the caseIgnoreMatch, caseIgnoreListMatch, telephoneNumberMatch, caseExactIA5Match and caseIgnoreIA5Match, multiple adjoining whitespace characters are treated the same as an individual space, and leading and trailing whitespace is ignored.

Clients MUST NOT assume that servers are capable of transliteration of Unicode values.

Substring Matching: caseIgnoreSubstringsMatch

Description:

The Substring Assertion is encoded according to the following BNF:

      substring = [initial] any [final]
      initial = value
      any = "*" *(value "*")
      final = value

The production is UTF-8 encoded string. Should the backslash or asterix characters be present in a production of , they are quoted as described in section 4.3.

Servers SHOULD be capable of performing the following matching rules, which are used in substring filters.
