inetorgperson.schema

["Zamangoer, Ferruh" <ferruh.zamangoer@materna.de>]

Hi all,

I want to use inetorgperson.schema, but following error occurs 

/usr/local/etc/openldap/schema/inetorgperson.schema: line 143: AttributeType
not found: "audio"

objectclass     ( 2.16.840.1.113730.3.2.2
    NAME 'inetOrgPerson'
        DESC 'RFC2798: Internet Organizational Person'
    SUP organizationalPerson
    STRUCTURAL
        MAY (
                audio $ businessCategory $ carLicense $ departmentNumber $
                displayName $ employeeNumber $ employeeType $ givenName $
                homePhone $ homePostalAddress $ initials $ jpegPhoto $
                labeledURI $ mail $ manager $ mobile $ o $ pager $
                photo $ roomNumber $ secretary $ uid $ userCertificate $
                x500uniqueIdentifier $ preferredLanguage $
                userSMIMECertificate $ userPKCS12 )
	    )


Where is the attribute audio defined in another schema ?????
