Hi I have installed samba-3.0.11-5.of.2 on RHEL-3.windows 2003 is being used for authentication (security=ADS). i have a share 'test' and have given rwx permission to parent group and one other group.SGID bit is set on this share. when someone from either group create a Microsoft Excel file in this share it is writable but after someone else write to this file, read only bit gets set on this file and no one can write to this file.it shows Sharing violation error. it does not happens on normal text files. please provide some hint. Regards Ashish
