Permission denied after using setfacl

Question

There are 3 users: A, B, C.

A has mydir in its home folder/home/A/mydir

B can read the /home/Acontents

C can read and write /home/Acontent

I tried this way:

setfacl -Rm u:B:r /home/A/
setfacl -Rm u:C:rw /home/A/

su B
ls /home/A
ls: cannot access /home/A: Permission denied
mydir
cd /home/A
-bash: cd: /home/A/: Permission denied

getfacl / home / A:

getfacl: Removing leading '/' from absolute path names
# file: home/A
# owner: A
# group: A
user::rwx

user:C:rw-

Answer 1

As tampis allready said, in order to go to the directory (or list its contents or read the file in it) in linux, you need to execute permissions for this directory. Change the text setfaclto the following:

setfacl -Rm u:B:rx /home/A/
setfacl -Rm u:C:rwx /home/A/

Answer 2

"setfacl -m  u:B:r-x /home/A"
