Description From 2014-11-18 12:03:30
openssh-clients-5.9p1-alt7 in SimplyLinux 7.0.4

I've installed SimplyLinux 7.0.1 (x86_64), and I'm using the default DE.

I have a password-protected SSH key.

On login, I'm asked the password (by the GUI dialog).

Then, whenever I do ssh, I'm asked the password again by the GUI dialog.

But I'm not authenticated then! (This is the problem!)

Something is wrong with ssh-agent and ssh-askpass in the default DE.

If I invoke them manually, there are no problems:

[imz@z ~]$ killall ssh-agent 
[imz@z ~]$ ssh-agent -u -d &
[1] 3164
[imz@z ~]$ SSH_AUTH_SOCK=/home/imz/.ssh/agent; export SSH_AUTH_SOCK;
echo Agent pid 3164;

[imz@z ~]$ ssh-add </dev/null

This is how it fails to use the key (after the correct password was entered in
the GUI, 2 times: on DE login, and when doing ssh).

If I run ssh-add in terminal in this case, it works:

[imz@z ~]$ ssh vaio
Agent admitted failure to sign using the key.

[imz@z ~]$ ssh-add
