Files & Folders not inheriting ACL permissions when opened, modified or created in shared SMB in Big Sur

Trying to transfer (upgrade) a shared file server to a new Mac Mini M1 on Big Sur

1- File sharing is gone from Mac Os Server App

So no more Make Inherited Entries Explicit. option!

2- I know I have to change the ACL Value of all those files

different groups have access to different files....

4- I have found this here https://discussions.apple.com/thread/250537136

chmod =a# 0 "thegroup allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit" BadShare

Would love to chat with Strontium90 to help me understand

And trying to apply it in Big Sur and it's not working.

Here is what I have tried:

Ex: I created a group name: test

created a test folder named: testfld

I used Dropbox to back all the files...

chmod =a# 0 “test allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit"

/Users/server/Dropbox/BigBackUp/Testfld

And it does not work

any help would be appreciated

Thank you

Found my Solution:

Sharing file over SMB and Big Sur

in Terminal

sudo chmod +a "group:yourgroupname allow readsecurity,readattr,readextattr,list,search,read,execute,writeattr,writeextattr,delete,add_file,add_subdirectory,delete_child,write,append,file_inherit,directory_inherit" DirectoryNameToApplyACLTo

Copy-paste the above line in a text or in Notes line is longer than appearing above
Make sure quotes are Quotes ( " )
Try to make your group name without any space, it worked better for me.
Drag and drop the folder in the terminal (DirectoryNameToApplyACLTo) to avoid mistakes
Make sure there is a space between _inherit" and (DirectoryNameToApplyACLTo)
In File Sharing Preference right-click the folder and Apply Permissions to Enclosed items.
Test.

Ex:

groupe name: Test
Folder name: Test2
Location: Guest / public / Test2

Terminal:

sudo chmod +a "Test allow readsecurity,readattr,readextattr,list,search,read,execute,writeattr,writeextattr,delete,add_file,add_subdirectory,delete_child,write,append,file_inherit,directory_inherit" /Users/Guest/Public/test2

Thanks to Strontium90 for pointing me in the right direction.

Apple is making it just a little harder than it was on OS 6.5 and a Mac plus!

iTunes is gone

iPhoto also

Searching for a solution on the web used to be easy.

Try searching for a duplicate in Music on Google!!!

or duplicate in Photo on Google!!!

Sharing files was also easy...With OS X Server

With a little sauce, everything finally worked...

I'm sure it will help someone else.
