TCP/IP Tutorial and Technical Overview - IBM Redbooks

Some example searches expressed informally are:
► Find the postal address for cn=John Smith,o=IBM,c=UK.
► Find all the entries that are children of the entry ou=ITSO,o=IBM,c=US.
► Find the e-mail address and phone number of anyone in an organization
whose last name contains the characters “miller” and who also has a fax
number.
To perform a search, the following parameters must be specified:
Base A DN that defines the starting point, called the base
object, of the search. The base object is a node within the
DIT.
Scope Specifies how deep within the DIT to search from the
base object. There are three choices:
470 TCP/IP Tutorial and Technical Overview
baseObject Only the base object is examined.
singleLevel Only the immediate children of the base
object are examined; the base object
itself is not examined.
wholeSubtree The base object and all of its
descendants are examined.
Alias dereferencing Specifies if aliases are dereferenced. That is, the actual
object of interest, pointed to by an alias entry, is
examined. Not dereferencing aliases allows the alias
entries themselves to be examined. This parameter must
be one of the following:
neverDerefAliases
Do not deference aliases.
derefInSearching
Dereference aliases only when
searching subordinates of the base
object.
derefFindingBaseObj
Dereference aliases only when
searching for the base object, but not
when searching subordinates of the
base object.
derefAlways Always dereference aliases.
Size Limit The maximum number of entries that should be returned
as a result of the search.
