I have a CentOS linux web server in which I have multiple web sites. I have many website programmers now doing the coding for all the sites. How can I provide a key-based authentication for the programmers in such a way that they have access only to /home folder ? They should be able to access only all the files inside /home and able to modify it. This is cPanel server in which all the sites comes under /home directory. Currently they are using separate passwords for every site. If I could give access to my developer inside /home folder, they would be able to do edit all the sites easily rather than having separate password for each site (eg : /home/site1 or /home/site2). Please share your ideas on the same. Thanks,
