Chef and Windows Active directory

Hi,

I’ve been bootstrapping Windows servers in a lab environment using local admin accounts and this has worked fine (bootstrap command is run from a Windows server). However, we’re now trying to integrate this into production and would like to use an AD account when bootstrapping the server. This is failing with the following error:

D:\chef-repo>knife bootstrap windows winrm 10.175.1.21 --winrm-user=“domain\build_chef” --winrm-password="password"
Bootstrapping Chef on 10.175.1.21
ERROR: Failed to authenticate to [“10.175.1.21”] as domain\build_chef
Response: Bad HTTP response returned from server (401).
ERROR: Batch render command returned

On the server I am trying to bootstrap, I get this error in the security logs:
Account For Which Logon Failed:
Security ID: NULL SID
Account Name: Build_Chef
Account Domain: BMGUK

Failure Information:
Failure Reason: An Error occured during Logon.
Status: 0xC000005E
Sub Status: 0x0

Detailed Authentication Information:
Logon Process: NtLmSsp
Authentication Package: NTLM
Transited Services: -

Key Length: 0

Any ideas on why this is failing? And why is it trying to use NTLM rather than Kerberos?

The user is in the local administrators group so has access to the server.

Thanks
Tom

NtLmSsp is the auth service under windows, it doen’t really tell if it
is authenticating with kerberos or NTLM scheme.

Try using user@domain.fully.qualified.name or escape the backslah to
avoid escaping the B of Build_chef: domain\Build_hef.

If the domainBuild_chef is only a mail typo, try the @ form for the
username which should works.

Tom, on which machine are you getting those auth logs? On the DC, or on the
server you’re truing to join to the domain?

The first thing to check is if you can issue commands via knife winrm, so
rather than a bootstrap, can you issue a simple command like “echo” on the
system? If not, then you probably need to enable “allow unencrypted” on
your winrm listener on the remote system. To confirm one thing though: is
the machine already joined to the domain and that domain user a member of
the local admins group?

If that is working, then it sounds like the credentials aren’t making it
off the system when talking to the DC. In that case, enabling CredSSP is
required, e.g. in powershell

ls WSMan:\localhost\Service\Auth\CredSSP

If that shows false, try using set-item to set it to true.

Thanks.

Hi Adam,

The auth logs are from the server we are trying to bootstrap. This server is already on the domain and we can log in to it using domain accounts. The chef user is a domain account which is a member of the local admin group on the server we’re bootstrapping.

We are able to run this from the admin server:
winrs -u:domain\build_chef -p:password -r:10.175.1.21 dir
but fails when running this:
knife winrm -m 10.175.1.21 -P ‘password’ -x domain\build_chef dir

CredSSP was disabled, but enabling it in powershell and winrm doesn’t appear to have done anything.

Tensibai - we’ve tried domain\user, domain\user and user@domain (the latter doesn’t pass the domain through, the user appears as user@domain). None of these have worked either.

Thanks
Tom

Tom, do you have allow_unencrypted and basic_auth set to true? You
shouldn’t need the latter unless something is strange, but just to debug,
can you see if those are set, and if not, set them and retry?

System.String Basic GPO true

System.String Kerberos true

Could you paste the result of winrm get winrm/config from the target
server ?

I would suspect the allow unencrypted parameter as Adam says before.

Hope you’ll find, debuging winrm is a high PITA, but its really nice
once it works :stuck_out_tongue:

P.S: Just to be sure, in the form user@domain, domain is the fully
qualified domain name right ?

Hi,

Both AllowUnencrypted and basic_auth are set to true.

Winrm commands will work, it’s when using knife this seems to break. So I’m not really sure which of these we should be troubleshooting.

When using user@domain, it’s actually user@domain.groupmailto:user@domain.group we use, so yeah, it’s fully qualified.

Thanks
Tom

Hi,

I’ve been bootstrapping Windows servers in a lab environment using local admin accounts and this has worked fine (bootstrap command is run from a Windows server). However, we’re now trying to integrate this into production and would like to use an AD account when bootstrapping the server. This is failing with the following error:

D:\chef-repo>knife bootstrap windows winrm 10.175.1.21 --winrm-user=“domain\build_chef” --winrm-password="password"
Bootstrapping Chef on 10.175.1.21
ERROR: Failed to authenticate to [“10.175.1.21”] as domain\build_chef
Response: Bad HTTP response returned from server (401).
ERROR: Batch render command returned

On the server I am trying to bootstrap, I get this error in the security logs:
Account For Which Logon Failed:
Security ID: NULL SID
Account Name: Build_Chef
Account Domain: BMGUK

Failure Information:
Failure Reason: An Error occured during Logon.
Status: 0xC000005E
Sub Status: 0x0

Detailed Authentication Information:
Logon Process: NtLmSsp
Authentication Package: NTLM
Transited Services: -
Package Name (NTLM only): -
Key Length: 0

Any ideas on why this is failing? And why is it trying to use NTLM rather than Kerberos?

The user is in the local administrators group so has access to the server.

Thanks
Tom
