deleting values from multivalued attribute

Hello list, is it possible to perform the deletion of only a certain number of values, from a multivalued attribute, without having to perform full deletion and then adding the ones we'd like to keep? example, entry has: mail: user(a)example.com mailAlternateAddress: first.last(a)example.com mailAlternateAddress: flast(a)example.com mailAlternateAddress: firstl(a)example.com I would like to be able to remove flast(a)example.com but keep the rest of the addresses, using a single ldap operation, ending up with mail: user(a)example.com mailAlternateAddress: first.last(a)example.com mailAlternateAddress: firstl(a)example.com Best Regards, Hugo Monteiro. -- fct.unl.pt:~# cat .signature Hugo Monteiro Email : hugo.monteiro(a)fct.unl.pt Telefone : +351 212948300 Ext.15307 Web : http://hmonteiro.net Divisão de Informática Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa Quinta da Torre 2829-516 Caparica Portugal Telefone: +351 212948596 Fax: +351 212948548 www.fct.unl.pt apoio(a)fct.unl.pt fct.unl.pt:~# _
