All, I am running SAMBA on Red Hat EL 5 with AD. I want the users not to have to login when they map the drive on the windows machine but I am having an issue. The idmap backend appears to not be working. Wbinfo -u and -g work, getent passwd and getent group works as well. When I login to my windows domain, I am prompted for a username and password. Any help would be greatly appreciated! Thanks, -Kevin
