modify: incorrect PDU structure

[Arvid R. <ar...@Te...>]

Hi fellow perl-ldapers,

I get the errormessage
	"Unrecognized version number or incorrect PDU structure"
when doing a a modify with the following code:
#-------------------------------------------------------------------------
$result = $ldap->modify($dn,
                        changes => [
                              delete => [ $attrib => $attrib_value_orig ],
                              add    => [ $attrib => $attrib_value ]
                        ]
                    );
#-------------------------------------------------------------------------

while a simple replace like the following works (but I can't use that
with multivalued attributes, can I?):

#-------------------------------------------------------------------------
$result = $ldap->modify($dn, replace => { $attrib => $attrib_value } );
#-------------------------------------------------------------------------

I'm using perl-ldap-0.19 and openldap 1.2.11

Happy ldaping
 Arvid
