The simplest way to authenticate against windows-domain with linux-boxes. i am doing this by head, hoping i indicate it right. ->execute systec-config-auth, this offers you 2 menues: menu 1) choose winbind, configure it regarding your domain-information menu 2) choose samba, configure it regarding to your domain-information. check, whether winbind-information are in there too.. you are finished and your linux-box should authenticate against a windows-domaincontroller or samba-server. ah yes: leave authenticate to "user" - do not change to domain - for me, this works perfectly. You will finally have to start winbind: 'service winbind start' let me know, if it works. HTH Roger
