Samba ask for credential to explore resource.

Hello everyone.
I use OMV 3.0.80 and configure SMB\CIFS plugin to share several folders.

From windows I have to insert credential to see what is sharing form OMV.
Even if I disable every shared folders windows ask for credential.

I would like configure SMB that everyone see what is sharing but when user like to insert to shared folder then he have to insert credential (for every folder other credential).

When I enable guest access to shared folder then I can see whole shared folder but when I want to insert to this folder windows inform me that I don't have permissions.
He not ask for credential only informs that user doesn't have permissions.

I tested this option before but when I set "Only Guests" in shared folder then of course everyone see whole shared folders but when I try enter to this shared folder windows display message:

"Windows cannot acces to \\myserver\shared_folder"
"You don't have permisions to \\myserver\shared_folder"

Maybe something's wrong in ACL of this folder ?

I don't want to disable password and make folder read/write for every one.
I think you don't understand me.

Now I have in LAN OMV Samba server called for example MyServer.
On this server I have create several users called: aaa, bbb, ccc
Also I create several shared folders for example folder1, folder2, folder3

On OMV GUI in Acces Rights Manager -> Shared Folders I have create three shared folders "Folder1" "Folder2" ... with standard permissions Admin: read/write Users: read/write Other: Read only

In "Privileges" I select
read/write for user aaa for folder1
read/write for user bbb for folder2
read/write for user ccc for folder3

In ACL I select
for folder1
owner: aaa read/write/execute
groups: users read/execute
others: read only
Replace all existing permissions: YES
Recursive: YES
In Users/Group permission also select user aaa for red/write

The same settings for user bbb and ccc for folder2 and folder 3

I go to Services -> SMB/CIFS and enable this service
Now I go to Shares and make three shared folders folder1 and so one.
Now in Windows when I want to explore \\MyServer\ then Windows prompt me for credentials

I don't want to Windows ask me for user\password like now.
I want everyone can acces to \\MyServer\ and can see three shared folders: folder1, folder2, folder3
When I want to insert to \\MyServer\folder1 Windows should prompt for credentials.
When I insert user aaa and his password I can explore folder1 but when I want explore folder2 I should insert user bbb and his password.
What I do wrong.

Even if I delete whole shared folders from Services -> SMB/CIFS -> Shares and want to access \\MyServer\ Windows ask for credentials but he shouldn't because there isn't any shared folder.
