红帽全球峰会5.3. IdM DNS records for external DNS systems
After installing an IdM server without integrated DNS, you must add LDAP and Kerberos DNS resource records for the IdM server to your external DNS system.
The ipa-server-install installation script generates a file containing the list of DNS resource records with a file name in the format /tmp/ipa.system.records.<random_characters>.db and prints instructions to add those records:
Please add records in this file to your DNS system: /tmp/ipa.system.records.6zdjqxh3.dbThis is an example of the contents of the file:
_kerberos-master._tcp.example.com. 86400 IN SRV 0 100 88 server.example.com.
_kerberos-master._udp.example.com. 86400 IN SRV 0 100 88 server.example.com.
_kerberos._tcp.example.com. 86400 IN SRV 0 100 88 server.example.com.
_kerberos._udp.example.com. 86400 IN SRV 0 100 88 server.example.com.
_kerberos.example.com. 86400 IN TXT "EXAMPLE.COM"
_kpasswd._tcp.example.com. 86400 IN SRV 0 100 464 server.example.com.
_kpasswd._udp.example.com. 86400 IN SRV 0 100 464 server.example.com.
_ldap._tcp.example.com. 86400 IN SRV 0 100 389 server.example.com.注意
After adding the LDAP and Kerberos DNS resource records for the IdM server to your DNS system, ensure that the DNS management tools have not added PTR records for ipa-ca. The presence of PTR records for ipa-ca in your DNS could cause subsequent IdM replica installations to fail.
