Hello,
I am trying to use the acl, but I have not been successful.
I modified the /etc/fstab file:
from
dev/mapper/VolGrpUsr_DK0-home /home ext4 default 1 2
to
dev/mapper/VolGrpUsr_DK0-home /home ext4 rw,acl 1 2
and
mount -v -o remount /home
mount: /dev/mapper/VolGrpUsr_DK0-home mounted on /home.
This what I get:
/dev/mapper/VolGrpUsr_DK0-home on /home type ext4
(rw,relatime,seclabel,stripe=2,data=ordered)
This is the same with default or with acl.
There is not indication that the acl are working!
Do I need to do something else?
Thank.

If rw and acl are default modes, then you won't see anything special.
Test it with the setfacl command on something.

Yes,
I did:
setfacl -m u:amsterdam:r out.pdf
but masterdam cannot access to the file:
ls /home/pdupre/out.pdf
ls: cannot access /home/pdupre/out.pdf: Permission denied
or
I/O Error: Couldn't open file '/home/pdupre/out.pdf'

Just like "normal" linux permissions the user also has to have access to the
full directory structure.
If user amsterdam doesn't have permission to descend into /home/pdupre then they
won't get access to out.pdf.

It seems most people that say they are "done talking about it" never really are
until given the last word.

Yes,
I did:
setfacl -m u:amsterdam:r out.pdf
but masterdam cannot access to the file:
ls /home/pdupre/out.pdf
ls: cannot access /home/pdupre/out.pdf: Permission denied

Please don't top post. It makes the context hard to understand. I've put some
context back up the top.
setfacl has the charming feature that changes have no effect until it is
invoked with the --mask option.
Please retry your test like this:
setfacl -m u:amsterdam:r --mask out.pdf
I am privately imagining that this "feature" allows one to do several changes
to an ACL but not have them take effect until the last one., thus permitting
atomic effects from incremental changes. But it is really annoying.
BTW, "I/O Error"? If that is an OS error something if bad. On the other hand it
might just be a mislead application error string. Your "Permission denied"
message is what I would expect.
