Summary:
In this validation procedure, the technical contact sends the link to the domain information of the commissioned domain to the certification authority.

The technical contact receives an e-mail with further details and information to the e-mail address stored in the myServerPass customer portal.

The following steps are required:

  1. Step: Contact a Whois information service to request domain owner information for your commissioned domain.
  2. Step: After submitting the request, the domain owner deposited in the Whois receives an e-mail with a link to this information.
  3. Step: Use the button [Link input] in the myServerPass customer portal under < My Domains> to insert the link.
  4. Step: The registration authority verifies the information and further processes the order.

Summary:
A defined, one-time string will be installed in the form of a text file on an HTTP / HTTPS web server and checked by the registration authority.

The technical contact receives an e-mail with further details and information to the e-mail address stored in the myServerPass customer portal.

The following steps are required:

  1. Step 1: Copy the unique string of this email.
  2. Step 2: With a text editor, create a text file with the name "serverpassdv.txt" from this string.
  3. Step 3: This text file must be placed under one of these two paths:
    http://<CommonName>/.wellknown/pki-validation/serverpassdv.txt
    https://<CommonName>/.wellknown/pki-validation/serverpassdv.txt
  4. Step 4: Confirm the embedding of the text file under < My Domains> in the myServerPass customer portal (confirmed button).
  5. Step 5: The registration authority checks the entry and further processes the order.

The validation email is valid for 30 days. After the expiration of this period of validity, a reply will no longer be accepted and the order will not be further processed.

Summary:
An E-mail will be sent to clearly defined e-mail recipients for each commissioned domain and the reply will be verified by the Registration Authority.

During the online order process, you must select an e-mail-address for the domain to which you have access.

The accepted e-mail addresses for the commissioned domains are:

  • admin@yourdomain.com
  • administrator@yourdomain.com
  • hostmaster@yourdomain.com
  • postmaster@yourdomain.com
  • webmaster@yourdomian.com

After sending the online order, an e-mail with a validation code is sent to the selected e-mail address. The recipient confirms control of the domain by entering the validation code received in the myServerPass customer portal.

The validation code is valid for 30 days. After this validity period has expired, a reply is no longer accepted and the order is not processed further.

Note for certificates with multiple domain names:

For each commissioned domain name requested (e.g. SAN/SAN EV certificate), the domain validation described must be conducted, that means, that you will receive a separate e-mail for each main domain entry.

The following specifications apply: The verification of a high-level domain including underlying sublevel domains.

Example:
The verification for example.com includes, for example, "www.example.com" and "markt.region.example.com". Conversely, this is not the case.

 

Summary:
In this validation procedure, domain control is proven through the deliberate insertion of unique information in the DNS.

The technical contact receives an e-mail with further details and information to the e-mail address stored in the ServerPass customer portal.

The following steps are required:

  1. Step 1: The e-mail recipient makes an additional DNS entry of type TXT according to the received e-mail.
  2. Step 2: This entry has to be confirmed under < My Domains> in the myServerPass customer portal (confirmed button).
  3. Step 3: The registration authority checks the entry and continues to process the order.

The validation email is valid for 30 days. After the expiration of this period of validity, a reply will no longer be accepted and the order will not be further processed.

When issuing OV (Organization Validation) and EV (Extended Validation) server certificates, the domain control / domain ownership of the client must also be checked. Thereby, T-Systems follows the guidelines set by the CA/B Forum (CA Browser Forum) in the form of the Baseline Requirements.

Detailed information can be found in the current version of the document "Baseline Requirements" of the CA/B Forum (cabforum.org).

Due to the EU-DSGVO (EU Data Protection Regulation), which came into effect on 25.05.2018 as well as changes in the Baseline Requirements, alternative procedures must be used because some test options are no longer available or are of limited disposal.

These changes, which affect domain ownership / domain control, now require your input in any case. You can currently select from the following options:

After the online order, you will receive an e-mail with further information.

If a reissue does not use a new key, domain revalidation is not required.

When ordering certificates with sublevel names (e.g. c.example.de), it is sufficient, if the domain example.de is validated.  Conversely, the validation of (e.g. c.example.de) is not sufficient for the domain example.de.
