[Samba] Crazy problem with excel and acls

[Nestor Chacon]

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.
