i am trying to set up a samba ads server called "networking" on FC4 . When I try to join the w2k3 domain(net ads join) , I get errors. However the copmuter is listed in active directory but I cant log into the networking server. I am trying not to use netbios. It works if I do not use these lines in global: name resolve order = host disable netbios = yes errors: Using short domain name -- MYDOMAIN [2006/03/04 22:26:46, 0] libads/kerberos.c:get_service_ticket(337) get_service_ticket: kerberos_kinit_password NETWORKING$@MYDOMAIN.COM@MYDOMAIN.COM failed: Preauthentication failed Joined 'NETWORKING' to realm 'MYDOMAIN.COM' here is smb.conf: [global] name resolve order = host disable netbios = yes workgroup = MYDOMAIN realm = MYDOMAIN.COM netbios name = NETWORKING preferred master = no server string = Samba file and print server security = ADS encrypt passwords = yes log level = 3 log file = /var/log/samba/%m max log size = 50 winbind separator = + wins support = no idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes winbind use default domain = yes --------------------------------- Brings words and photos together (easily) with PhotoMail - it's free and works with Yahoo!
