Self-signed Certificate
In compliance with UC APL requirements, PKI Self-signed Certificates are supported for the both the Default
Management and IP Network Services.
A mixture of Self-signed and CA-signed Certificates is supported, however a CA-signed certificate will
always override a Self-signed Certificate.
Self-signed Certificate Creation
Self-signed Certificates are created during:
● Initial system start-up before any CA-signed Certificates have been installed.
● IP Network Services creation.
● Network Services updates that result in Host Name changes.
● Daily validity checks of Self-signed Certificates.
● Backup and Restore of the system configuration
Self-signed Certificate field values are automatically inserted when the certificate is created:

Both the Issuer and Issued To fields have the same values.
CN = host name of the service name

OU = Self Signed Certificate

Note: The value of CN is derived from the IP Network Service Name, while the
values of DC, OU and O are hard coded.
For a full description of these fields see RFC 5280.
