Hi All,

I’m setting up an SFTP Server with CentOS 7. I created 4 Users SFTP only. Call them are A,B,C,D.
I followed this guide to install:
https://www.techrepublic.com/article/how-to-set-up-an-sftp-server-on-linux/

Problem here : If follow exactly this guide, each user can only access their folder. I want User D can access and manage files in folder users A,B,C .
How do I configure that?
Pls kindly help me this case. Thank you all very much!
