Error of The permissions on the certificate Template do not allow the current user to enroll for this type of certificate. 0x80094012 (-2146877422)

Hi There,

I have a complex issue related to the Certificate template. the enviroment at my end is as follows-

I have 2 machines -

1) windows server 2012 R2 , a domain controller having the certificate enrollment custom application, that enroll the certificate to the user.

2) windows server 2008 R2 , a member server having the Certificate Authority configured.

i dont want to add authenticated user group in my certificate template . so i have created a new Certificate Template , removed the Authenticated Users group from the ACL of this template and added a new user group with the read and enroll permission on it.

when i tried to enroll the certificate from 2012 R2 machine i am getting the error of The permissions on the certificate Template do not allow the current user to enroll for this type of certificate. 0x80094012 (-2146877422)

i tried to find out the reason , then from one of the blog i come to know this-

CA itself is included in the Authenticated User’s group. Once we remove this group from the certificate template, the Certificate Authority stops contacting with the template, as a result we get the error in the system log as well as in the revoked certificates list–Certificate Request Denied So if you do not want to add Authenticated user group in the template, you have to add the CA computer machine’s name in the template with the read permission on it.

i tried it but still i am facing the issue.

one more thing is if i tried to enroll certificate using mmc without my certificate enrollment custom application, enrollment is taking place.

Kindly help me to resolve this.

Regards

Sonam

Hi
I have "old" PKI and "NEW" PKI working together while NEW PKI issue new certificates and OLD PKI is fading slowly

All Computers uses old machine authentication certificates
New computers or renewed certs shall be issued from the NEW PKI

it means that for some time computers shall use old and new certificates, a fact that is a problem for us

Is it possible to enforce all computers to enroll NEW certs to all computers at once ?

Windows Server Security, 2008/2012 R2 Standard editions

We are continuously getting SSH, Sql Server and ftp requests and may be more, on few of our Web Servers... We managed to work on ftp by installing filezilla and configuring autoban ip after failed authentications. How this can be done for other services to protect the complete server?

More Details: We are a team of web developers and have a total of 7 servers, 4 of them are on Windows 2008 R2 & rest are on 2012 R2. In these servers 2 are used for development and testing & 5 are on production environments. We use Sql browser, RDP, FTP & http(s) so we cannot totally close these ports.

Couple of weeks back: Where is a lot going on these server so we could not monitor everything. 2 weeks before a couple of websites went down, later by checking these websites were there but the files got renamed like index.html to index.html'''''' and also found some new folders with files written in chinese or japanese or something like that. We cannot block countries as we have some ecommerce sites running and have business with them.

Now: Now we disabled the previous admin account and created new ones. Also filezilla server is providing autoban which is proving good, things seems to be fine now but in event viewer security logs we daily found tons of failed login attempts. Many of them are anonymous and does not showing any source ip address. We have tried cyberarms idds but that wasn't helpful with anonymous attempts.

CA request - Windows Server 2012 - Subject Alternate Name

Hi,
 
On 2008 R2 SubCA I used .inf file to create certificates with SAN. I used the following extension:
 
[Extensions]
 2.5.29.17 = "{text}"
 _continue_ = "dns=name.domain.com$dns=othername"
 
This does not seem to work on a 2012 SubCA. Is there any changes in how to get SAN in the certificate?

Is Web Application Proxy enough as a secure Reverse Proxy/publishing solution

$

Hello,

What are people's thoughts on using the Web Application Proxy role as a reverse proxy with only a Firewall between it and the internet...?

We need to replace our ISA 2006 boxes and I have been advocating using WAP with ADFS.
However other 'Reverse Proxy' solution available seem to have more capabilities then just WAP and a Firewall; without  we leave ourselves exposed. For instance FortiNet's product FortiWeb has the following 'additional' capabilities:

  • Protection for application layer attacks (SQL Injection, XSS, PHP/OS/LDAP/RFI/LFI injection and more)
  • Automatic layer 7 anomaly-based application baselining and threat detection
  • Data Leak Prevention (CC, SSN, server/application leakage)
  • IP Reputation

Are these required? Does WAP provide these capabilities but use different terminology?

SubCA Certificate cannot be renewed

$

Dear Friends,

I've got a quite urgent problem. Maybe you can help me...

 

Here’s my problem:

I need to renew a sub-ca cert. To do so I followed a huge amount of blogs and tutorials, for example:

http://support.risualblogs.com/blog/2014/05/13/renew-issuingsubordinate-ca-certificate/

 

But in every Tutorial the writers are able to choose an online CA or export the request by clicking Cancel in the following Step:

My problem is, that this window isn’t showing up. When I choose “No” in the Window before where he asks me whether to create a new key or not and continue, he is just starting the services again and nothing has changed. In the Properties of the sub-ca is still one cert which will expire soon:

 

When I try to renew it by using certutil, I get the following message:

PS C:\Users\administrator.CLOUD4YOU> certutil -renewcert ReuseKeys -f
CertUtil: -renewCert command FAILED: 0x8007139f (WIN32: 5023)
CertUtil: The group or resource is not in the correct state to perform the requested operation.


I’ve googled the error-message already, but none of the solutions applied for us.

 

When I try the 3<sup>rd</sup> option by renewing the cert with the same key over mmc -> Certificates, I get the same error as this writer: https://social.technet.microsoft.com/forums/windowsserver/en-US/90c78256-6291-4e6d-8dd8-82280cc00e69/unable-to-renew-subca but in our deployment the template was already activated

 

I really don’t know what to do next…  Do you have any idea?

 

Thanks in advance!

MS CS: Revert to Old CA Certificate

I had recently renew my Root CA certificate (renew key as well). I would like to check if there is any way to revert it back to the old Root CA cert with using the restore from backup option as we had already issued new certs signed by the new CA certificate.

CRM 2015 Outlook Plugin and SCCM 2012

$

Good Morning!

In need of some assistance from you more experienced SCCM admins. Let me quickly run down the steps of what I've done:

1) Created a network share for CRM 2015 that everyone can see
2) Ran the EXE from Microsoft and followed the instructions from them to create the CrmClient_32.msi 
3) In SCCM, created a new application, and linked the shared folder. SCCM auto-populated the install command, publisher data, etc. The only thing I added was "/s" for the MSI package to install

4) Created a Device Collection with one test PC that already has CRM 2013 installed

5) Deployed the application to the device collection with the following options:

Under Content Tab:

Content Location: \\networkshare\Installs\CRM2015
Persist content in the client cache is NOT checked
Allow clients to share content with other clients on the same subnet IS checked
Deployment options: Do not download content

Under the Programs Tab:

Installation program: msiexec /i /s "CrmClient_32.msi"
Installation start in: blank
Uninstall program: msiexec /x 

Run installation and uninstall program as 32-bit process on 64-bit clients IS checked


Under User Experience Tab:

Installation Behavior: Install for system
Logon requirement: Whether or not a user is logged on
Installation program "margin-bottom:9px;padding-right:0px;padding-font-family:Arial, Helvetica, sans-serif;font-size:14px;line-height:21px;word-wrap:break-word;color:#333333;">Maximum allowed run time ( 120 minutes)
Estimated installation time (0 minutes)

6) I schedule the install (for most applications I've seen this works best)

Now when I go to Monitoring, all I see is the deployment is "In Progress" and the category is "Waiting for content" 

I'm frustrated because I don't understand why this won't work. It seems so painless and the method I've described above works for almost any other application I've pushed out.

I'm all ears - is there anything you see that isn't correct? Any ideas or suggestions? If you've successfully pushed out CRM 2015 some how (even if it's not through SCCM), could you please share your solution?

Thank you so much! -Nick

AutoEnrollment Issue - Windows 7

$

Hello, 

I recently deployed a two tier PKI infrastructure; 2x Windows 2012 R2 CA servers, 1 Standalone Root CA (offline) and 1 Enterprise Subordinate CA 

I created a new User setting GPO to enable auto-enrollment which has been deployed throughout the organization; I setup a new certificate template with domain users / authenticated users Read, Enroll and Auto-enroll permissions.  

When I logon a client machine I do not see any certificates; I ran certutil -pulse which ran without any issues and verified  the correct autoenrollment registry setting is listed 0x0000007.  But when I go into certmgr.msc and try to "Automatically Enroll and retrieve certificates"  it says "Certificate types are not available" then I select show all templates and under the template with auto-enroll enabled the following error appears:

"Cannot find the original signer; Information about available certificates cannot be obtained at  this time.  This type of certificate has already been installed on your computer" 

I am kinda lost.. right now im digging through event logs and verifying certificate template settings.  Any suggestions would be greatly appreciated.

Thank You
