I have a 2.2.6pre2 (mandrake 9.0) install that I have migrated a bunch of users files to, from a dying win2k Active Server. It's primarily for storage but I hope to support interactive logins later on. I created unix accounts and home directories and copied the files over from the win2k box and am having the linux server authenticate against the remaining (working) win2k AS box. The home directories mount fine from the linux server. For illustrative purposes lets call these machines win2kstorage (dying machine), linuxstorage, and win2kauth. On the windows clients: when the user files were on win2kstorage they were seen as owned by "domain\user". After moving the files to the linux storage, the files show "linuxstorage\user" as the owner of the files. Win2k doesn't have a problem with letting users create, modify, or delete those files, but certain programs (cough esri cough) seem to be using old file routines that balk at the different ownership. question 1. is this normal behavior, even though samba is authenticating to the domain it's changing ownership info of files to correspond to the unix users? question 2. is there a way to map the unix users to their domain ownership counterparts (I don't think this is a simple smbuser issue, but I could be wrong) so that on the windows clients it still sees "domain\user" as the owner of all created files? or to map UIDs on unix to their users SID on win2k? Any help would be appreciated Thanks Barry Hunter Priest
