FOG Client 0.11.16 : Authentication ERROR: Could not authenticate

[alexandre-nerriere]

Hello, I have this problem with an host. I’m using the last FOG version. Can you help me please ?

@alexandre-nerriere Did you reinstall your FOG server after this client got the fog-client software installed?

I am asking because when installing a FOG server it generates a self hosted certificate authority (CA) as well as certificates and keys. When installing the fog-client on a machine it “pins” itself to that CA and won’t connect to any other.

Take a look at this: https://wiki.fogproject.org/wiki/index.php?title=Migrate_FOG#If_old_server_was_FOG_1.3.0.2B

If it’s just one single client you see this issue on I would just uninstall and re-install the fog-client software on this machine. But my guess is you are having this on several machines.

@Sebastian-Roth Yes I have reinstalled my FOG server but i have reinstall my FOG client too. I have just for the moment one client because i need to test FOG for my company.

@alexandre-nerriere I suggest you uninstall the fog-client on the machine again and see if you need to manually remove the CA certificate from the windows cert store. Open certlm.msc as well as certmgr.msc and navigate to the “Trusted Root Certification Authorities -> Certificates” folder. Here you might find “FOG Server CA” and “FOG Project”. Remove those from both the cert stores (certlm and certmgr), reboot the client and re-install fog-client software.

As well make sure you click “Reset Encryption Data” in FOG web UI -> host -> settings of this particular host!

@Sebastian-Roth I just make the test, but it’s the same thing. Maybe it’s comes from the image I’ve deployed on this host ?

I just make the test, but it’s the same thing.

What do you mean by that? Did you follow the instructions on removing the client and certificates and re-installing? When the fog-client installer runs it says “Pinning to FOG server” and it should download the certs!

I just noted one part of the log messages that I might have missed when reading those first. “Certificate is not from FOG CA”… Do you use custom SSL certificates by any chance??

[alexandre-nerriere]

@Sebastian-Roth yes I have follow your instructions. For FOG we don’t use custom SSL certificate.

@Sebastian-Roth It’s worked ! I’ve done your solution three times in a row and it seems worked.
Thanks you for your job and your disponibility.
