[Samba] Two Questions concerning samba - file access times - two instances on one server

[Laurenz, Dirk]

Hello everybody,

i have two questions concerning samba.

1st Topic - file times
	NTFS has three file times for each file,
	the create time, the change time and the
	access time. The create time will never be
	modified, the change time will be changed
	every time you save a file, the access time
	will be changed every time you access (read)
	a file. If i access a file on a samba share,
	the access time will be modified correctly,
	but if i resave a file, the create time is
	also changed although i would expect that only
	the change time will be modified. I found some
	parameters concerning file times, but none
	of them changes the behaviour. I used the following
	parameters:
	dos filetimes = yes
	dos filetime resolution = yes
	Has anyone a suggestion, which parameters must be
	set, to get the NTFS behaviour? B.t.w., the underlying
	filesystem is an ext3 with acl,user_xattr mount options.

2nd Topic - two instances on one server
	I have successfully running two instances on one server.
	Both are members in an NT4 Domain and every thing works
	right, but local username resolution and groupmappings.
	Normal startup order is:
	- Instance A
	- Instance B
	Setting some groupmappings works fine for Instance B.
	if i restart Instance A but not B, the groupmappings/usermappings 
	from Instance A get effective. And thats very bad....
	If i restart afterwards Instance B, everything is fine.
	I guess, this is a winbind issue. The problem is, I think,
	the last started winbindd wins...

	Here are my conf's (INSTANCE A and B)
