Certificates

Last update: November 19 2024

Certificates

Two types of certificates are used when working with federations:

• certificate of credential suppliers — A certificate that is issued on the credential provider side and added when configuring the federation in the control panel. Without the certificate, the federation will not work;
• certificates for signing requests — An optional certificate that is issued on the Selectel side if the federation checkbox is selected Sign authentication requests.

Certificates of credential providers⁠

You issue a certificate from the credentialing vendor and add it to the federation in Selectel. The certificate is used for data authentication when authenticating a user in the control panel.

You can create a federation without a certificate and add it later, but a federation without a certificate will not work. You can add up to 10 certificates for one federation.

If a federation has multiple certificates, they will be applied sequentially: if a certificate has expired or is invalid, the next downloaded certificate will be applied.
