Problem

After I installed and setting google-authenticator packages, weird authentication related message keep shown when I use directory listing command on user's home directory.

I've tested on another owned directory but nothing happend unless home directory.

ls, dir and authentication works fine but still message are annoying me :

$ ls
cannot be satisfied by enabled authentication method?OAqsq

$ ls -al

drwxr-xr-x. 3 root root 20 10월 10 12:23 .. cannot be satisfied by enabled authentication method?OAqsq

$ dir
cannot be satisfied by enabled authentication method33OAqsq
