Description

Hi,
 
I tried guacd with last commit at (GUACAMOLE-745) and my ssh connexions don't work anymore.
 
I have error:

---

guacd[5107]: INFO: Auth key successfully imported.
guacd[5107]: ERROR: Public key authentication failed: Unable to extract public key from private key.

---

 
I tried to convert ssh private key (RSA) to format OPENSSH ("BEGIN OPENSSH PRIVATE KEY"), but same result/error.
 
Thanks for your help.
Lionel
