Partial Date Or Time Matching Rules

OpenDS provides the partialDateAndTimeMatchingRule matching rule for performing a substring match on dates in GeneralizedTime attributes:

( 1.3.6.1.4.1.26027.1.4.7
NAME 'partialDateAndTimeMatchingRule'
SYNTAX 1.3.6.1.4.1.1466.115.121.1.24 )

This matching rule applies to attributes with a GeneralizedTime syntax, but the value is not a generalized time. Instead, it specifies a pattern for the date, composed of one or more sequences of an integer followed by a tag. The currently supported tags are Y, M, D, h, m, and s .

The following examples use the attribute birthDate (described in http://tools.ietf.org/html/draft-gryphon-ldap-schema-vcard4-00) with the following definition:

attributeTypes: ( 1.3.6.1.4.1.33592.1.3.2 NAME 'birthDate' 
DESC 'birthday' 
EQUALITY generalizedTimeMatch 
ORDERING generalizedTimeOrderingMatch
SYNTAX .3.6.1.4.1.1466.115.121.1.24 
USAGE userApplications SINGLE-VALUE )

For example, the following filter matches all users born on September 21st.

(birthDate:1.3.6.1.4.1.26027.1.4.7:=09M21D)

As another example, the following filter matches all users born in 1965:

(birthDate:1.3.6.1.4.1.26027.1.4.7:=1965Y)

The following search operation returns all entries with a birthday the fourteenth day of any month:

$ ./ldapsearch -p 1389 -h localhost -D "cn=Directory Manager" -w password \
  -b "dc=example,dc=com" \
  "(birthDate:1.3.6.1.4.1.26027.1.4.7:=14D)" birthDate
