To delete the CA-signed certificate from the Manager, perform the following steps:

Steps:

  1. In the Manager, go to Manager → <Admin Domain Name> → Setup → Certificates. Select GUI Certificate tab.

    The GUI Certificate tab is displayed.

  2. Click GUID-9A719AD5-F6BE-4CD4-9311-CC6655DF9B70-low.png.

    The Confirmation dialog box opens.

    Note

    The GUID-9A719AD5-F6BE-4CD4-9311-CC6655DF9B70-low.png option is available only when there is a CA-signed certificate in the Manager. You cannot delete the self-signed certificate in the Manager.

  3. Click OK to confirm deletion.

    Note

    When the CA-signed certificate in the Manager is deleted, automatically a self-signed certificate is used for the web server authentication.

  4. Restart the Manager server.

    The Manager server automatically starts using self-signed certificate to establish trust with the client systems.
