Fixed upstream ipa-4-6: https://pagure.io/freeipa/c/b3dfc13f36de365b78bfbf6ac0fda2549d134739 ipa-4-5: https://pagure.io/freeipa/c/55b7f588d0eced7e4b7840d808138eb798347d77 Answering the question on how to reproduce this: There's an LDIF file that was previously used, with the following contents: """ dn: cn=ipa-http-delegation,cn=s4u2proxy,cn=etc,$SUFFIX changetype: modify add: memberPrincipal memberPrincipal: HTTP/$FQDN@$REALM # ipa-cifs-delegation-targets needs to be an ipaAllowedTarget for HTTP # delegation but we don't add it here as an LDIF because this entry may # already exist from another replica, or previous install. If it is missing # then it will be caught by the update file 61-trusts-s4u2proxy.update dn: cn=ipa-ldap-delegation-targets,cn=s4u2proxy,cn=etc,$SUFFIX changetype: modify add: memberPrincipal memberPrincipal: ldap/$FQDN@$REALM """ Just perform ldapmodify with appropriately replaced variables on master server and try to install replica against such a master. Previously, the observed failure would happen, now the installation should pass. version: ipa-server-4.5.0-22.el7_4.x86_64 Steps: 1. Added the entry for replica in directory server on master. [root@master ~]# cat a.ldif dn: cn=ipa-http-delegation,cn=s4u2proxy,cn=etc,dc=testrelm,dc=test changetype: modify add: memberPrincipal memberPrincipal: HTTP/replica.testrelm.test dn: cn=ipa-ldap-delegation-targets,cn=s4u2proxy,cn=etc,dc=testrelm,dc=test changetype: modify add: memberPrincipal memberPrincipal: ldap/replica.testrelm.test [root@master ~]# ldapmodify -h master.testrelm.test -p 389 -D "cn=directory manager" -w Secret123 -f a.ldif modifying entry "cn=ipa-http-delegation,cn=s4u2proxy,cn=etc,dc=testrelm,dc=test" modifying entry "cn=ipa-ldap-delegation-targets,cn=s4u2proxy,cn=etc,dc=testrelm,dc=test" [root@master ~]# 2.
