NAMENet::LDAP::Schema − Load and manipulate an LDAP v3 Schema
SYNOPSIS​ use Net::LDAP; ​ use Net::LDAP::Schema; ​ ​ # ​ # Read schema from server ​ # ​ $ldap = Net::LDAP−>new ( $server ); ​ $ldap−>bind ( ); ​ $schema = $ldap−>schema ( ); ​ ​ # ​ # Load from LDIF ​ # ​ $schema = Net::LDAP::Schema−>new; ​ $schema−>parse ( "schema.ldif" ) or die $schema−>error;
DESCRIPTION​Net::LDAP::Schema provides a means to load an LDAP schema and query it for information regarding supported objectclasses, attributes and syntaxes.
METHODSWhere a method is stated as taking the 'name or OID' of a schema item (which may be an object class, attribute or syntax) then a case-insensitive name or raw OID (object identifier, in dotted numeric string form, e.g. 2.5.4.0) may be supplied. Each returned item of schema (e.g. an attribute definition) is returned in a HASH. The keys in the returned HASH are lowercase versions of the keys read from the server. Here's a partial list (not all HASHes define all keys) although note that RFC 4512 permits other keys as well: ​ name ​ desc ​ obsolete ​ sup ​ equality ​ ordering ​ substr ​ syntax ​ single−value ​ collective ​ no−user−modification ​ usage ​ abstract ​ structural ​ auxiliary ​ must ​ may ​ applies ​ aux ​ not ​ oc ​ form all_attributes ( ) all_ditcontentrules ( ) all_ditstructurerules ( ) all_matchingrules ( ) all_matchingruleuses ( ) all_nameforms ( ) all_objectclasses ( ) all_syntaxes ( ) Returns a list of all the requested types in the schema. attribute ( NAME ) ditcontentrule ( NAME ) ditstructurerule ( NAME ) matchingrule ( NAME ) matchingruleuse ( NAME ) nameform ( NAME ) objectclass ( NAME ) syntax ( NAME ) Returns a reference to a hash, or undef if the schema item does not exist. NAME can be a name or an OID. ​ $attr_href = $schema−>attribute( "attrname" ); dump ( ) Dump the raw schema information to standard out. dump ( FILENAME ) Dump the raw schema information to a file. ​ $result = $schema−>dump ( "./schema.dump" ); If no schema data is returned from directory server, the method will return undefined. Otherwise a value of 1 is always returned. error ( ) Returns the last error encountered when parsing the schema. may ( OBJECTCLASS ) Given an argument which is the name or OID of a known object class, returns a list of HASHes describing the attributes which are optional in the class. ​ @may = $schema−>may ( $oc ); ​ # First optional attr has the name '$may[0]−>{name}' must ( OBJECTCLASS ) Given an argument which is the name or OID of a known object class, returns a list of HASHes describing the attributes which are mandatory in the class. ​ @must = $schema−>must ( $oc ); parse ( MESG ) parse ( ENTRY ) parse ( FILENAME ) Takes a single argument which can be any of, a message object returned from an LDAP search, a Net::LDAP::Entry object or the name of a file containing an LDIF form of the schema. If the argument is a message result from a search, ​Net::LDAP::Schema will parse the schema from the first entry returned. Returns true on success and undef on error. superclass ( NAME ) Given an argument which is the name or OID of a known objectclass, returns the list of names of the immediate superclasses. attribute_syntax ( NAME ) Given an attribute name, return the actual syntax taking into account attribute supertypes. matchingrule_for_attribute ( NAME, RULE ) Given an attribute name and a matching rule (equality, ​substr, etc), return the actual rule taking into account attribute supertypes.
