ACL Permission

[ashraful@localhost ~]$ setfacl -m u:user1:rwx File1.Txt

This is My OutPut:

==============

[ashraful@localhost ~]$ getfacl File1.Txt
file: File1.Txt
owner: ashraful
group: ashraful
user::rw-
user:ashraful:rwx
user:user1:rwx
user:user2:--x
user:user3:r--
group::rw-
mask::rwx
other::r--

I Switch my user To user1:

==============================

[user1@localhost Documents]$ getfacl File1.txt

file: File1.txt
owner: ashraful
group: ashraful
user::rw-
group::rw-
other::r--

I apply Red,Write and Excutieve
But I see only Red,Write.
And I can't also Write This File;

[user1@localhost Documents]$ vi File1.txt
[user1@localhost Documents]$ cat >> File1.txt

bash: File1.txt: Permission denied

How Can I solve this Problem.

Thanks
