红帽全球峰会第 4 章 Installing an IdM server: With integrated DNS, without a CA
Installing a new Identity Management (IdM) server with integrated DNS has the following advantages:
- You can automate much of the maintenance and DNS record management using native IdM tools. For example, DNS SRV records are automatically created during the setup, and later on are automatically updated.
- You can configure global forwarders during the installation of the IdM server for a stable external internet connection. Global forwarders are also useful for trusts with Active Directory.
- You can set up a DNS reverse zone to prevent emails from your domain to be considered spam by email servers outside of the IdM domain.
Installing IdM with integrated DNS has certain limitations:
- IdM DNS is not meant to be used as a general-purpose DNS server. Some of the advanced DNS functions are not supported. For more information, see DNS services available in an IdM server.
This chapter describes how you can install a new IdM server without a certificate authority (CA).
You need to provide the certificates required to install an Identity Management (IdM) server without a certificate authority (CA). By using the command-line options described, you can provide these certificates to the ipa-server-install utility.
You cannot install a server or replica using self-signed third-party server certificates because the imported certificate files must contain the full CA certificate chain of the CA that issued the LDAP and Apache server certificates.
- The LDAP server certificate and private key
-
--dirsrv-cert-filefor the certificate and private key files for the LDAP server certificate -
--dirsrv-pinfor the password to access the private key in the files specified in--dirsrv-cert-file
-
- The Apache server certificate and private key
-
--http-cert-filefor the certificate and private key files for the Apache server certificate -
--http-pinfor the password to access the private key in the files specified in--http-cert-file
-
- The full CA certificate chain of the CA that issued the LDAP and Apache server certificates
-
--dirsrv-cert-fileand--http-cert-filefor the certificate files with the full CA certificate chain or a part of it
-
You can provide the files specified in the --dirsrv-cert-file and --http-cert-file options in the following formats:
- Privacy-Enhanced Mail (PEM) encoded certificate (RFC 7468). Note that the Identity Management installer accepts concatenated PEM-encoded objects.
- Distinguished Encoding Rules (DER)
- PKCS #7 certificate chain objects
- PKCS #8 private key objects
- PKCS #12 archives
You can specify the --dirsrv-cert-file and --http-cert-file options multiple times to specify multiple files.
- The certificate files to complete the full CA certificate chain (not needed in some environments)
-
--ca-cert-filefor the file or files containing the CA certificate of the CA that issued the LDAP, Apache Server, and Kerberos KDC certificates. Use this option if the CA certificate is not present in the certificate files provided by the other options.
-
The files provided using --dirsrv-cert-file and --http-cert-file combined with the file provided using --ca-cert-file must contain the full CA certificate chain of the CA that issued the LDAP and Apache server certificates.
- The Kerberos key distribution center (KDC) PKINIT certificate and private key
If you have a PKINIT certificate, use the following 2 options:
-
--pkinit-cert-filefor the Kerberos KDC SSL certificate and private key -
--pkinit-pinfor the password to access the Kerberos KDC private key in the files specified in--pkinit-cert-file
-
If you do not have a PKINIT certificate and want to configure the IdM server with a local KDC with a self-signed certificate, use the following option:
-
--no-pkinitfor disabling pkinit setup steps
-
