I have an issue that I;m going round in circles with, I hope you can help. The Set up: Server 1 (CIFS Client) - CentOS 6.3 AD integrated uing Samba/Winbind & idmap_ad Server 2 (CIFS Server) - CentOS 6.3 AD integrated uing Samba/Winbind & idmap_ad All users (apart from root) are AD authenticated and this, including groups, etc works happily. What's working: I have created a share on Server 2: [share2] path = /srv/samba/share2 writeable = yes Permissions on the share: drwxrwx---. 2 root domain users 4096 Oct 12 09:21 share2 I can log into a Windows machine as user5 (member of domain users) and everything works as it should, for example: If I create a file it shows the correct permissions and attributes on both the MS and the Linux sides. Where I Fall Down: I mount the share on Server 1 using: # mount //server2/share2 /mnt/share2/ -o username=cifsmount,password=blah,domain=blah Or using fstab: //server2/share2 /mnt/share2 cifs credentials=/blah/.creds 0 0 This mounts fine, but.... If I log su, or log onto server 1 as a normal user (say user5) and try to create a file I get: #touch test touch test touch: cannot touch `test': Permission denied Then if I check the folder the file was created but as the cifsmount user: -rw-r--r--. 1 cifsmount domain users 0 Oct 12 09:21 test I can rename, delete, move or copy stuff around as user5, I just can't create anything, what am I doing wrong? I'm guessing it's something to do with the mount action as when I log onto server2 as user5 and access the folder locally it all works as it should. Can anyone point me in the right direction?
