Bug ID 1496397: Allowing entry of a Subject-Alternative-Name (SAN) for certificate and CSR creation

Last Modified: Jun 04, 2025

Affected Product(s):
F5OS Velos(all modules)

Fixed In:
F5OS-C 1.8.0, F5OS-A 1.8.0

Opened: Jan 26, 2024

Severity: 3-Major

Symptoms

There is no method available for inputting the SAN field during the creation of certificates or CSR.

Impact

The option to include the SAN field in certificates and/or certificate request is not available.

Conditions

While creating a CSR through system aaa tls create-csr in ConfD.

Workaround

To add an SAN, you need to edit the /etc/pki/tls/openssl.cnf file and add it. However, this may not be effective for certain software that does not accurately read the configuration file.

Fix Information

A new SAN field has been implemented, which is mandatory, and allows users to enter a value in the field. However, if the value “none” is used, the field can be omitted. Additionally, to allow entry of the SAN, a default tls certificate is created in /etc/auth-config/default/f5os.cert that has the SAN populated with the hostname and management-ip values. In the absence of a user-provided self-signed certificate, the http-server will automatically use the default certificate. As this is a new feature, back-porting to older versions has not been implemented and would be difficult and complex.
