This bug is created as a clone of upstream ticket: https://fedorahosted.org/freeipa/ticket/6588 From issue reported here: https://www.redhat.com/archives/freeipa-users/2016-December/msg00395.html {{{ Configuring the web interface (httpd). Estimated time: 1 minute [1/19]: setting mod_nss port to 443 [2/19]: setting mod_nss cipher suite [3/19]: setting mod_nss protocol list to TLSv1.0 - TLSv1.2 [4/19]: setting mod_nss password file [5/19]: enabling mod_nss renegotiate [6/19]: adding URL rewriting rules [7/19]: configuring httpd [8/19]: setting up httpd keytab [9/19]: setting up ssl [error] NotFound: no such entry Your system may be partly configured. Run /usr/sbin/ipa-server-install --uninstall to clean up. ipa.ipapython.install.cli.install_tool(Replica): ERROR no such entry ipa.ipapython.install.cli.install_tool(Replica): ERROR The ipa-replica-install command failed. See /var/log/ipareplica-install.log for more information }}} During installation replica cannot find HTTP service and installer fails. This is not 100% reproducible, but is is caused by replication when http entry is not replicated on time from master server. Steps are following (IPA 4.4): 1. install DS on replica 1. create the http service entry on master for replica (using remote_api; install_http_certs(config, fstore, remote_api)) 1. install other services, including http 1. http service fails to install in case that ldap entry from is not replicated yet to replica from master This is reproducible mainly with ca-less install because in that case replication has less time to replicate entries from master. Proposed fix: wait after install_http_certs until http service entry is replicated
fixed upstream ipa-4-4: 3d0a0728766aed7245427b9eaf210e31fd40e440 wait_for_entry: use only DN as parameter 5bddcdb47b40baeae7379e00e8d87297ed3f1cd4 Wait until HTTPS principal entry is replicated to replica 74020d07dbf14202f696a0c8521829abc735d4c7 Use proper logging for error messages
