I have a samba server with windbind, and support for acls. When a user modify one excel file with excel 2000 the file permissions change to "user::r--" If the excel version is 97 this problem does not exist and the file permisssions are the default "user::rwx". the smb.conf is this: [global] workgroup=XXXX realm=XXX.ES server string = servidor de ficheros samba security= ADS log level = 3 log file = /var/log/samba/%m max log size = 50 printcap name = cups preferred master = No idmap uid = 10000-20000 idmap gid = 10000-20000 winbind separator = + winbind cache time = 120 printing = cups print command lpq command = %p lprm command create mask = 0700 inherit acls = yes map acl inherit = yes I rpobe to change the parameter "create mask", "acl compatibility", and "acl group control" with no results. Thanks for all and sorry for my poor english.
