Hi all, I have a system/process in place where I mount remote shares(with EFS) on windows boxes from Linux servers and rsync data to them. The Windows machines now are windows 2000 pro and I need to migrate them to Windows XP or even Vista later in the future. The Windows 2000 Pro machines which work are set up like so: Local folder path: c:\datashare Share: \\machinename\share$ AD domain: 2003 --------->ACL on folder: local admins -FULL | system -FULL |service account -FULL | User account -READ ------------>Share ACL: Everyone FULL --------------->EFS is setup like so: logon with service account, and set EFS on folder, backup CERT and import CERT to users account. This all works perfect in windows 2000, but in windows XP Microsoft tightened up EFS in addition to above you have to: set "trusted for delagation" on both the user and computer account at the domain level. I found this artical and many others Like it would give the Hex codes to downgrade the Symetrical crypto: http://support.microsoft.com/kb/329741 and also tryed the system Policys and forced: (use FIPS crypto) I am mounting with mount.cifs like so: mount -t cifs //machinename/share /home/Nex6/winmount -o username=accountnamehere I am greatly suspecting it is the "trusted for delagation" requirements for EFS remote sharing: here is a the EFS docs: http://technet.microsoft.com/en-us/library/bb457116.aspx got this section: Remote EFS Operations in a File Share Environment Does anyone have any insight into this? Thanks -Nex6
