Ok, after working on this I turn to this mailing list for help. I have a Redhat linux system which I have compliled samba-2.2.8a-1.i386 on. I want to authenticate a share on a linux server with a windows 2000 domain controller(mixed mode). Samba alone works fine authenticating against smbpasswd. I compiled samba with: --with-pam, --with-winbind, --with-winbind-auth-challenge. Configure, make, and make install go fine. I copy the libs over, add 3 lines to my /etc/nsswitch.conf: passwd: files winbind shadow: files group: files winbind I start smbd, successfully join the domin, start nmbd and winbind and all is fine. I run wbinfo -u, wbinfo -g, wbinfo -a domainname\\user%pass and all comes out fine. So far so good. Now, I have a share setup in my smb.conf which I try to connect to from my Windows XP PC and it prompts me for a username and password, hmm this is not what I wanted, enter the information in as domainnam\username and password in the 2nd box. It does not work. Here is my smb.conf file modified from its original state to hopefully work with winbind: [global] winbind cache time = 10 winbind uid = 10000-20000 winbind gid = 10000-20000 winbind use default domain = yes workgroup = domainname name resolve order = hosts bcast wins lmhosts security = domain password server = domaincontroller1 encrypt passwords = yes [backup] comment = backup path = /home/backup browseable = yes public = no writable = yes printable = no valid users = myusername I even tried wbinfo -A but that seemed to not work either. Any comments, suggestions, or flames are welcome.
