NOTE: For systems running SUSE Linux Enterprise Server and Red Hat Enterprise Linux operating systems,
whenever there are new security updates to OpenJDK, you must install the latest supported OpenJDK 11.0.x JRE
binaries from the vendor's official repositories. For systems running on Microsoft Windows Server operating system,
you must log in to the Customer Portal of Red Hat and download the latest supported Windows OpenJDK 11.0.x
JRE Installer. The latest version of OpenJDK and the download link is available in the About page, and you can also
download the latest version of OpenJDK at https://access.redhat.com/products/openjdk.
4. When you finish setting options in the Server Preferences window, click Apply.
NOTE: You must restart the Server Administrator web server for the changes to take effect.
X.509 Certificate Management
NOTE: You must be logged in with Administrator privileges to perform certificate management.
Web certificates are necessary to ensure the identity of a remote system and ensure that information exchanged with the
remote system are not viewed or changed by others. To ensure system security, it is recommended that:
You generate a new X.509 certificate, reuse an existing X.509 certificate or import a certificate chain from a Certification
Authority (CA).
All systems that have Server Administrator installed have unique host names.
To manage X.509 certificates through the Preferences home page, click General Settings, click the Web Server tab, and
click X.509 Certificate.
The following are the available options:
Generate a new certificate Generates a new self-signed certificate used for SSL communication between the server
running Server Administrator and the browser.
NOTE:
When using a self-signed certificate, most web browsers display an untrusted warning as the self-signed
certificate is not signed by a Certificate Authority (CA) trusted by the operating system. Some secure browser settings
can also block the self-signed SSL certificates. The Server Administrator web GUI requires a CA-signed certificate for
such secure browsers.
Certificate Maintenance Allows you to generate a Certificate Signing Request (CSR) containing all the certificate
information about the host required by the CA to automate the creation of a trusted SSL web certificate. You can retrieve
the necessary CSR file either from the instructions on the Certificate Signing Request (CSR) page or by copying the entire
text in the text box on the CSR page and pasting it in the CA submit form. The text must be in the Base64encoded format.
NOTE:
You also have an option to view the certificate information and export the certificate that is being used in the
Base64encoded format, which can be imported by other web services.
Import certificate chain Allows you to import the certificate chain (in PKCS#7 format) signed by a trusted CA. The
certificate can be in DER or Base64-encoded format.
Import a PKCS12 Keystore Allows you to import a PKCS#12 keystore that replaces the private key and certificate
used in Server Administrator web server. PKCS#12 is public keystore that contains a private key and the certificate for a
web server. Server Administrator uses the Java KeyStore (JKS) format to store the SSL certificates and its private key.
Importing a PKCS#12 keystore to Server Administrator deletes the keystore entries, and imports a private key and certificate
entries to the Server Administrator JKS.
NOTE: An error message is displayed if you either select an invalid PKCS file or when you type an incorrect password.
SSL Server Certificates
Server Administrator Web server is configured to use the industry-standard SSL security protocol to transfer encrypted
data over a network. Built on an asymmetric encryption technology, SSL is widely accepted for providing authenticated and
encrypted communication between clients and servers to prevent eavesdropping across a network.
An SSL-enabled system can perform the following tasks:
Authenticate itself to an SSL-enabled client
Allow the two systems to establish an encrypted connection
The encryption process provides a high level of data protection. Server Administrator uses the most secure form of encryption
generally available for Internet browsers in North America.
