\&\f(CW\*(C`Net::LDAP::Schema\*(C'\fR provides a means to load an \s-1LDAP\s0 schema and query it
for information regarding supported objectclasses, attributes and syntaxes.
.SH "METHODS"
.IX Header "METHODS"
Where a method is stated as taking the 'name or \s-1OID\s0' of a schema item (which
may be an object class, attribute or syntax) then a case-insensitive name
or raw \s-1OID \s0(object identifier, in dotted numeric string form, e.g. 2.5.4.0)
may be supplied.
.PP
Each returned item of schema (eg an attribute definition) is returned
in a \s-1HASH.\s0 The keys in the returned \s-1HASH\s0 are lowercase versions of
the keys read from the server. Here's a partial list (not all HASHes
define all keys) although note that \s-1RFC 4512\s0 permits other keys as
well:
