chapter 3.3.10 :
3.3.10. Enhanced Guide
A value of the Enhanced Guide syntax suggests criteria, which consist
of combinations of attribute types and filter operators, to be used
in constructing filters to search for entries of particular object
classes. The Enhanced Guide syntax improves upon the Guide syntax by
allowing the recommended depth of the search to be specified.
The LDAP-specific encoding of a value of this syntax is defined by
the following ABNF:
EnhancedGuide = object-class SHARP WSP criteria WSP
SHARP WSP subset
object-class = WSP oid WSP
subset = "baseobject" / "oneLevel" / "wholeSubtree"
criteria = and-term *( BAR and-term )
and-term = term *( AMPERSAND term )
term = EXCLAIM term /
attributetype DOLLAR match-type /
LPAREN criteria RPAREN /
true /
false
match-type = "EQ" / "SUBSTR" / "GE" / "LE" / "APPROX"
true = "?true"
false = "?false"
BAR = %x7C ; vertical bar ("|")
AMPERSAND = %x26 ; ampersand ("&")
EXCLAIM = %x21 ; exclamation mark ("!")
The <SHARP>, <WSP>, <oid>, <LPAREN>, <RPAREN>, <attributetype>,
and
<DOLLAR> rules are defined in [RFC4512 <http://tools.ietf.org/html/rfc4512>].
The LDAP definition for the Enhanced Guide syntax is:
( 1.3.6.1.4.1.1466.115.121.1.21 DESC 'Enhanced Guide' )
Example:
person#(sn$EQ)#oneLevel
The Enhanced Guide syntax corresponds to the EnhancedGuide ASN.1 type
from [X.520 <http://tools.ietf.org/html/rfc4517#ref-X.520>]. The EnhancedGuide type
references the Criteria ASN.1
type, also from [X.520 <http://tools.ietf.org/html/rfc4517#ref-X.520>]. The <true>
rule, above, represents an empty
"and" expression in a value of the Criteria type. The <false> rule,
above, represents an empty "or" expression in a value of the Criteria
type.
