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

METHODS

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.
