4. When I try to discover certificates issued by Microsoft Certificate Authority, the discovery fails. How do I resolve this?

To successfully discover, import and manage certificates from your Certificate Store and those issued by your Microsoft Certificate Authority (MS CA), make sure that you use your domain administrator account as Key Manager Plus' service logon account. In case you use a domain service account to run Key Manager Plus, make sure you've configured it in the local admin group beforehand. Restart Key Manager Plus after the configurations are made for the changes to take effect then perform MS CA discovery.

SSH Key Management

1. Are there any differences in the way SSH user accounts and SSH service accounts are managed using Key Manager Plus?

No, Key Manager Plus adopts the same approach for managing SSH user accounts and SSH service accounts. The only difference is that during resource discovery, if service / root account credentials are provided to establish connection with the resource, you acquire extended privileges to import and manage keys from all user accounts in the resource. 

Whereas, when connection to the resource is established using user account credentials, you get key management privileges only for SSH keys present in that particular account. 

2. Is there any way to view SSH keys that were not rotated? 

Yes. We have a dashboard that displays the number of keys that were not rotated for the predefined time period as specified in the notification policy. You can drill down from here to obtain further information about these keys by clicking on the widget. 

SSL Certificate Management

1. Is there any certificate type that Key Manager Plus is incompatible with?

No. Key Manager Plus supports all X.509 certificate types.

2. Is it possible to automatically identify and update the latest version of certificates in Key Manager Plus' certificate repository?

Yes. You can create scheduled tasks to perform automatic certificate discovery through which you can import and replace old certificates from target systems with their updated versions in Key Manager Plus' certificate repository. Click here for detailed explanation on schedule creation.

3. Does the Linux version of Key Manager Plus support certificate discovery from Active Directory and MS Certificate Store?

No, it doesn't. The AD User Certificate and MS Certificate Store tabs appear only in the Windows version of Key Manager Plus.

4. Is it possible to track the expiry of certificates with the same common name in Key Manager Plus' certificate repository?

Key Manager Plus differentiates certificates by their common names and records certificates with same common names as a single entry in its certificate repository. We've designed it this way because Key Manager Plus licencing is based on the number of certificates and we don't want customers spending many licence keys for the same certificate. 

However, if there's a need to manage both certificates separately, you can do so by listing it as a separate entry in Key Manager Plus' certificate repository. Once listed, the newly added certificate will be counted for licensing.

To add certificate with the same common name as a separate entry in certificate repository,

  • Navigate to SSL → Certificates and click Certificate History icon on the right side of the table view.
  • Click Certificate Settings icon beside the required version of the certificate and click Manage Certificate.
  • The selected version is listed as a separate certificate in the certificate repository.
  • In case you want to manage only one version of the certificate, click Certificate Settings icon beside the required version and choose Set as current certificate option. The chosen version is set for management.

5. How to import private key for a certificate?

Follow the steps below to import a certificate's private key into Key Manager Plus.

  • Navigate to SSL → Certificates tab.
  • Select the certificate for which you need to import the private key.
  • Choose Import Key option from the More top menu.
  • Browse for the file that contains the private key, enter the keystore password and click Import. The private key is imported and attached to the selected certificate.

5. I get an "encryption key file not available" error in/Wrapper.log file when trying to start / restart Key Manager Plus.

"Error: PMP encryption key file is not available in E:\Manage Engine Key Manager\IPB Key\pmp_key.key INFO | jvm 1 | 2018/05/18 16:25:34 | Error: Exception while initializing PMP Cryptography. java.lang.Exception: PMP encryption key file is not available in E:\Manage Engine Key Manager\IPB Key\pmp_key.key"

The above issue occurs if there is a location mismatch of "pmp_key.key" file configured in "manage_key.conf" file and the actual path of the "pmp_key.key" file. 

To resolve the issue, follow the steps below and then restart Key Manager Plus.

  • Navigate to\Conf folder and look for the file named "pmp_key.key".
