ERROR: Could not get security token

Jordane

Hello to all,
I also have the Token.dat problem on my clients in my recently deployed FOG server.
I am on the dev-branch in version 1.5.9.239.
I have done all the tests on the forum and nothing works.
When I try to regenerate the certificates by rerunning ./install.sh -K and reinstall the agent, this is what comes up:

Then after a few syncs, still the same problem…

It’s been several days now that I’m doing all the topics present on the forum to unblock myself but I start to need help…
Thanks to you in advance

@Jordane Looks like the fog-client doesn’t use FIPS complient crypto but your system enforces this security standard: https://learn.microsoft.com/en-us/troubleshoot/system-center/orchestrator/exception-error-install-sma-web-service

Though it might also just be a question of libraries being FIPS certified or not: https://learn.microsoft.com/en-us/dotnet/framework/migration-guide/retargeting/4.7.2-4.8#managed-cryptography-classes-do-not-throw-a-cryptographyexception-in-fips-mode

The fog-client currently uses Rijndael(Managed class) and I guess we would need to switch to AES:
https://learn.microsoft.com/en-us/archive/blogs/shawnfa/the-differences-between-rijndael-and-aes
https://learn.microsoft.com/en-us/dotnet/api/system.security.cryptography.rijndaelmanaged?view=net-7.0

Possibly we cannot give you a quick solution or workaround on this. Maybe it’s a minor step to switch to a Aes class but I am not sure yet.

And then there might be a second issue as well. The error mentioned in the first code block (System.UnauthorizedAccessException: L'accès à la clé de Registre '230' est refusé.) points to registry access being blocked. Maybe this is caused by some kind of anti virus software?

Hello @Sebastian-Roth, Thank you for your reactivity.
Indeed, in the local security strategy of our clients, the FIPS encryption is activated.
But also the option, Configure the types of encryption allowed for Kerberos “AES256 and future”.
These are the options that would block me?
AES is not compatible with FOG services?
Is it possible to disable encryption from fog and the TOKEN function?
Ideally, it should communicate with clients without encryption.

Probably yes. And I really do understand your organization is forcing FIPS compliance.

AES is not compatible with FOG services?

Well, AES is actually a subset of the Rijndael implementation used in the fog-client. So it’s pretty close. I guess we can switch to using AES as I said before but not in a quick move! Needs code changes and testing.

I was going to open an issue report on github to keep track of this but turns out this has been around since a long time already as well as another forum topic (sounds like the fix isn’t that easy…)

Is it possible to disable encryption from fog and the TOKEN function?

No, not right now. One of my future plans was to remove the self made encryption from the fog-client/forproject code but switch to using HTTPS (enforced). This way we’d rely on state of the art crypto done by webservers and system crypto libraries. But that is even further away than switching to AES.

Ideally, it should communicate with clients without encryption.

I don’t get this. Why would you enforce FIPS compliance but then let the communication go unencrypted?!?!? Just doesn’t make sense to me.
