[quote=“Wolfbane8653, post: 42276, member: 3362”]From your comments [URL=‘http://fogproject.org/forum/threads/requests-for-wiki-access-ask-here.3811/page-2#post-42253’]here[/URL]. I am assuming that you have partly figured this out?
This error usually occurs due to the password not being encrypted correctly.[/quote]
That’s what one would think, but have triple checked the password, and got another person to check the encrypted password too.
But note I was using the old HostnameChanger and the new one. What error does indicate password not being encrypted correctly? Because I got different errors in both cases.

Look them up and you may have a better/clearer answer. The error codes you see are not FOG generated

Yep, they are generated by the old HostnameChanger. But the new one says this:
[CODE]16/02/2015 2:41 p.m. FOG::HostnameChanger Padding is invalid and cannot be removed.
16/02/2015 2:41 p.m. FOG::HostnameChanger at System.Security.Cryptography.RijndaelManagedTransform.DecryptData(Byte
[] inputBuffer, Int32 inputOffset, Int32 inputCount, Byte[]& outputBuffer, Int32 outputOffset, PaddingMode paddingMode,
Boolean fLast)
at System.Security.Cryptography.RijndaelManagedTransform.TransformFinalBlock(Byte[] inputBuffer, Int32 inputOffset,
Int32 inputCount)
[/CODE]As this is a different error message, does that mean that perhaps the encryption key of the new HostnameChanger is not the default one?
The old dll error message may seem to indicate I really have a problem with username/password, and I’ll check that again.
-
Which new one are you referring to?
The one from the github fogproject repo? Or the one from the fogservice repo?

The one I downloaded [URL=‘http://www.fogproject.org/forum/threads/active-directory-registration-not-working-windows-7-x64-client.11514/#post-42039’]from here in this thread[/URL].

OK, I had both the old dll and new dll in the directory, and it seems the service picks up both. That’s confusing. When using the new dll, I get this output (as already posted):

PS: it would be great if someone had a tip on how to compile HostnameChange.dll on Linux and produce a .dll that’s recognised. Then I could do some actual debugging!
-
And to repeat, with the original HostnameChange.dll I get this:

-
And your username field is not in the format domain/username?
-
Wow, compiliation actually works if I compile the FOGService.exe as well and copy that first. That’s great, can now do development on Linux.
-
[quote=“Tom Elliott, post: 43893, member: 7271”]And your username field is not in the format domain/username?[/quote]
No, it wasn’t. The domain name is automatically appended I saw already. The problem is that the password is garbled. When I hard-code it, everything works. Narrowing down to the culprit.
-
One thing I found out is that you cannot use the fully qualified name as domain in the active domain settings of a client. It must be in NetBios format. The reason is that the backend returns the user name as “<DOMAIN><username>” and if you have as domain “fog.example.org” you get a user name “fog.example.org\Administrator” for example, which won’t work.
-
The error, as everyone expected, was indeed in the encryption key. Somehow there is a difference between how HostnameChange encrypts/decrypts. I put in some debug code to encrypt my password and the encrypted hex is completely different. When I enter this encrypted hex in the active domain settings, everything works. Now tracking down why HostnameChange encrypts differently from the standard FOGCrypt (recompiled that from scratch as well, same output as standard binary).
-
This completely depends on your set ups environment yes there are times were having the fully qualified domain name works perfectly and there are times where it doesn’t I don’t know the specific settings that cause these issues or how to fix them but they are completely environmental
-
And here’s the very very nasty deal: you will have to run FOGCrypt.exe on the SAME computer as you want to decrypt on. I did run FOGCrypt.exe on different computers (Linux in this case), and it simply does not encrypt/decrypt the same. I don’t know why.
This may be an implementation issue in mono, maybe 32/64 bit??
But that’s all that there was to it. Bummer, this whole thing cost me a big amount of time of getting fog up and running. I would love to contribute back some patches and knowledge. But can’t get access to the Wiki to cleanup some obsolete comments.
And how do I propose patches? Is that against the git branch? For example the AbstractFOGService uses the wrong variable name, here’s patch:

And I would love to be allowed to add a patch that forbids people to use a DNS domain name in the active directory settings, or forbids to use the ‘’ character in the user name, both won’t work.

Hi Tom, I think I know exactly why and when they work now. For 1.2 the issue is that the domain name is prepended to the user name.
So you get domain fog.example.org, but the user name then becomes fog.example.org\Administrator. The [URL=‘https://msdn.microsoft.com/en-us/library/windows/desktop/aa370433(v=vs.85).aspx?f=255&MSPPError=-2147217396’]NetJoinDomain[/URL] domain call does not like that. [URL=‘http://www.fogproject.org/forum/threads/wiki-login.12416/#post-43951’]See my other post [/URL]where I touched upon this as well: I suggest FOG always uses the unqualified name for the domain name, and no domain name in the user name, far less confusing.
But there may be setups where a difference is required?? Not sure, but then the prepending logic must become way smarter, and the GUI should check for users who enter this wrong too.
You can lookup the Microsoft docs for [URL='https://msdn.microsoft.com/en-us/library/windows/desktop/aa370433(v=vs.85).aspx?f=255&MSPPError=-2147217396’]what’s allowed as value for the account name[/URL]:
[QUOTE][I]lpAccount[/I] [in]
A pointer to a constant null-terminated character string that specifies the account name to use when connecting to the domain controller. The string must specify either a domain NetBIOS name and user account (for example, [I]REDMOND\user[/I]) or the user principal name (UPN) of the user in the form of an Internet-style login name (for example, “[EMAIL]someone@example.com[/EMAIL]”). If this parameter is [B]NULL[/B], the caller’s context is used.[/QUOTE] -

One thing to add here: note that I did run EXACTLY the same code on Linux or the Windows machine (compiled myself with Mono). Got different encryption values in both cases.

regarding issues with the client, here’s something you might have missed. [url]http://fogproject.org/forum/threads/new-client-progress.12136/[/url]
the client is being rewritten from scratch.
btw, the domain\user issue is changed in the dev version of the code. in the current dev version of the code, the user field is checked for a \ or @. if either of those exist, the field is sent as is. if not, the domain is a added as domain\user. -

Maybe Mono uses a different compiler or libraries for Windows and Linux?
