This idea has been merged into another idea. To comment or vote on this idea, please visit ZOS-I-1844 Add ability for RACDCERT to handle multiple subject alternative names.

Enable z/OS to support multiple DNS hostname entries in the Subject Alt Name definitions in TLS certificates Merged

Currently, z/OS 2.4 supports only one single DNS hostname definition in TLS certificates.
For example, it is not possible to generate such certificates by calling RACDCERT GENCERT with ALTNAME and more than one DOMAIN keyword.
If you create such certificates on other platforms (for example with GSKit), and import them with RACDCERT IMPORT, all except one domain name are deleted.

z/OS RACF and the underlying products (AT-TLS, Communications Server, etc.) should support more than one DOMAIN / hostname definitions in TLS certificates.

    Thank you for submitting this requirement. It is a duplicate of RFE #115691. To clarify, when a certificate is added to RACF with multiple altnames, only one is displayed when issuing commands such as RACDCERT LIST. However the certificate is not modified, it still contains the complete extension.
