NAME
       ipa-cacert-manage - Manage CA certificates in IPA

SYNOPSIS
       ipa-cacert-manage [OPTIONS...] renew
ipa-cacert-manage [OPTIONS...] install CERTFILE

DESCRIPTION
       ipa-cacert-manage can be used to manage CA certificates in IPA.

COMMANDS
       renew  - Renew the IPA CA certificate

              This command can be used to manually renew the CA certificate of the IPA CA.

              When  the  IPA CA is the root CA (the default), it is not usually necessary to manually renew the CA certificate,
              as it will be renewed automatically when it is about to expire, but you can do so if you wish.

              When the IPA CA is subordinate of an external CA, the renewal process involves submitting a CSR to  the  external
              CA  and  installing  the  newly issued certificate in IPA, which cannot be done automatically. It is necessary to
              manually renew the CA certificate in this setup.

              When the IPA CA is not configured, this command is not available.

       install
              - Install a CA certificate

              This command can be used to install the certificate contained in CERTFILE as a new CA certificate to IPA.

COMMON OPTIONS
       --version
              Show the program's version and exit.

       -h, --help
              Show the help for this program.

       -p DM_PASSWORD, --password=DM_PASSWORD
              The Directory Manager password to use for authentication.

       -v, --verbose
              Print debugging information.

       -q, --quiet
              Output only errors.

       --log-file=FILE
              Log to the given file.

RENEW OPTIONS
       --self-signed
              Sign the renewed certificate by itself.

       --external-ca
              Sign the renewed certificate by external CA.

       --external-cert-file=FILE
              File containing the IPA CA certificate and the external CA certificate chain. The file is accepted in PEM and DER
              certificate and PKCS#7 certificate chain formats. This option may be used multiple times.

INSTALL OPTIONS
       -n NICKNAME, --nickname=NICKNAME
              Nickname for the certificate.

       -t TRUST_FLAGS, --trust-flags=TRUST_FLAGS
              Trust  flags for the certificate in certutil format. Trust flags are of the form "X,Y,Z" where X is for SSL, Y is
              for S/MIME, and Z is for code signing. Use ",," for no explicit trust.

              The supported trust flags are:

                     C - CA trusted to issue server certificates

                     T - CA trusted to issue client certificates

                     p - not trusted

EXIT STATUS
       0 if the command was successful

       1 if an error occurred
