I have a share that has been exported via NFS as well as shared using Samba 3.0. On the Windows side, all authentication is currently done using Winbind and Active Directory. On the standalone Samba server (also authenticated using Windbind) where the exported NFS resides, I have the same local Unix user (identified by the same name and UID/GID) that I have on each Unix (Mac/Linux) host that needs to access the NFS export. I also have name mappings setup in my smb.conf file. Currently, unless the file/directory is explicitly owned by "xuser", the unix hosts are not able to access that resource. Other than name mappings, I am not quite sure how to allow access to my NFS clients wanting to access these network shares without changing ownership of the user/group to my "xuser" The goal is that the unix username will map transparently to a Windows User/Group, but I am not quite sure how to manage this. My questions are as follows: Must IDMAPing be the same on all unix hosts before this will work?; and/or Can this be easily solved using the "net groupmap" command utility? Thanks in advance for your time and consideration. jyana
