Multi-valued attributes

Hi. Is it possible to use Multi-valued attributes? I have group1 NAS-Identifier =~ nas01|nas02 group2 NAS-Identifier =~ nas03|nas04 I'd like some users which are in group1 to access ALSO group2 nases. Is it possible to do that, without creating a dedicated group? thanks -- Lorenzo Milesi - lorenzo.milesi@yetopen.it GPG/PGP Key-Id: 0xE704E230 - http://keyserver.linux.it
