DESCRIPTION

26       "Net::LDAP::Schema" provides a means to load an LDAP schema and query
27       it for information regarding supported objectclasses, attributes and
28       syntaxes.
29

METHODS

31       Where a method is stated as taking the 'name or OID' of a schema item
32       (which may be an object class, attribute or syntax) then a case-
33       insensitive name or raw OID (object identifier, in dotted numeric
34       string form, e.g. 2.5.4.0) may be supplied.
35
36       Each returned item of schema (e.g. an attribute definition) is returned
37       in a HASH. The keys in the returned HASH are lowercase versions of the
38       keys read from the server. Here's a partial list (not all HASHes define
39       all keys) although note that RFC 4512 permits other keys as well:
40
41        name
42        desc
43        obsolete
44        sup
45        equality
46        ordering
47        substr
48        syntax
49        single-value
50        collective
51        no-user-modification
52        usage
53        abstract
54        structural
55        auxiliary
56        must
57        may
58        applies
59        aux
60        not
61        oc
62        form
63
64       all_attributes ( )
65       all_ditcontentrules ( )
66       all_ditstructurerules ( )
67       all_matchingrules ( )
68       all_matchingruleuses ( )
69       all_nameforms ( )
70       all_objectclasses ( )
71       all_syntaxes ( )
72           Returns a list of all the requested types in the schema.
73
74       attribute ( NAME )
75       ditcontentrule ( NAME )
76       ditstructurerule ( NAME )
77       matchingrule ( NAME )
78       matchingruleuse ( NAME )
79       nameform ( NAME )
80       objectclass ( NAME )
81       syntax ( NAME )
82           Returns a reference to a hash, or "undef" if the schema item does
83           not exist. "NAME" can be a name or an OID.
84
85            $attr_href = $schema->attribute( "attrname" );
86
87       dump ( )
88           Dump the raw schema information to standard out.
89
90       dump ( FILENAME )
91           Dump the raw schema information to a file.
92
93            $result = $schema->dump ( "./schema.dump" );
94
95           If no schema data is returned from directory server, the method
96           will return undefined.  Otherwise a value of 1 is always returned.
97
98       error ( )
99           Returns the last error encountered when parsing the schema.
100
101       may ( OBJECTCLASS )
102           Given an argument which is the name or OID of a known object class,
103           returns a list of HASHes describing the attributes which are
104           optional in the class.
105
106             @may = $schema->may ( $oc );
107             # First optional attr has the name '$may[0]->{name}'
108
109       must ( OBJECTCLASS )
110           Given an argument which is the name or OID of a known object class,
111           returns a list of HASHes describing the attributes which are
112           mandatory in the class.
113
114             @must = $schema->must ( $oc );
115
116       parse ( MESG )
117       parse ( ENTRY )
118       parse ( FILENAME )
119           Takes a single argument which can be any of, a message object
120           returned from an LDAP search, a "Net::LDAP::Entry" object or the
121           name of a file containing an LDIF form of the schema.
122
123           If the argument is a message result from a search,
124           "Net::LDAP::Schema" will parse the schema from the first entry
125           returned.
126
127           Returns true on success and "undef" on error.
128
129       superclass ( NAME )
130           Given an argument which is the name or OID of a known objectclass,
131           returns the list of names of the immediate superclasses.
132
133       attribute_syntax ( NAME )
134           Given an attribute name, return the actual syntax taking into
135           account attribute supertypes.
136
137       matchingrule_for_attribute ( NAME, RULE )
138           Given an attribute name and a matching rule ("equality", "substr",
139           etc), return the actual rule taking into account attribute
140           supertypes.
