[Bug 1067301] [NEW] ssh-add: Error reading response length from authentication socket.

[Lars Noodén]

Public bug reported:

ssh-add seems not to work with the confirmation (-c) option.  Trying to
require that identities be subject to confirmation when used brings up
the error "Error reading response length from authentication socket. "

 $ ssh-add -c /home/user/.ssh/key_rsa 
 Enter passphrase for /home/user/.ssh/key_rsa: 
 Error reading response length from authentication socket.
 Could not add identity: /home/user/.ssh/key_rsa

Addding keys not subject to confirmation when used works as normal:

 $ ssh-add  /home/user/.ssh/key_rsa 
 Enter passphrase for /home/user/.ssh/key_rsa: 
 Identity added: /home/user/.ssh/key_rsa (/home/user/.ssh/key_rsa)
