Configuration Process

Stopping PKI Server

To stop PKI server:

$ pki-server stop --wait

Configuring Certificate Request ID Generator

To disable the legacy ID generator for certificate requests:

$ pki-server ca-config-unset dbs.beginRequestNumber
$ pki-server ca-config-unset dbs.endRequestNumber
$ pki-server ca-config-unset dbs.requestIncrement
$ pki-server ca-config-unset dbs.requestLowWaterMark
$ pki-server ca-config-unset dbs.requestCloneTransferNumber
$ pki-server ca-config-unset dbs.requestRangeDN

To enable the RSNv3 ID generator for certificate requests:

$ pki-server ca-config-set dbs.request.id.generator random
$ pki-server ca-config-set dbs.request.id.length 128

Configuring Certificate ID Generator

To disable the legacy ID generator for certificates:

$ pki-server ca-config-unset dbs.beginSerialNumber
$ pki-server ca-config-unset dbs.endSerialNumber
$ pki-server ca-config-unset dbs.serialIncrement
$ pki-server ca-config-unset dbs.serialLowWaterMark
$ pki-server ca-config-unset dbs.serialCloneTransferNumber
$ pki-server ca-config-unset dbs.serialRangeDN

To enable the RSNv3 ID generator for certificates:

$ pki-server ca-config-set dbs.cert.id.generator random
$ pki-server ca-config-set dbs.cert.id.length 128

Restarting PKI Server
