Upstream ticket: https://pagure.io/freeipa/issue/6771 Needed for IPA to be performant. Fixed upstream master: https://pagure.io/freeipa/c/4ee7e4ee6d6500d8b8935c9033388adc4cdbe672 Fixed upstream ipa-4-5: https://pagure.io/freeipa/c/62d39385e20b3e1b059466f37cc063833355551e The difference between the option turned off and turned on is that when the option is turned off each request to the LDAP server requires a roundtripto the KDC to acquire an LDAP ticket, while that is not necessary with the option tunerd on. So to test you can simply compare two runs (before and after) where you use the IPA API (either vina ipa command or via web UI) to perform a number of operations as a specific test user. With the option turned off you should see in krb5kdc.log a request for an ldap/<ipa-server> ticket by 'test' user for each operation. Withthe option turned on you should see only one (or few) request in krb5kdc.log for all operations. HTH. See instructions above Verified using IPA version :: ipa-server-4.5.0-14.el7.x86_64 Marking BZ as verified. Performed sanity tests and integration tests for verification. As per Comment #7, seen only single ldap/<server> request for all operations. # tail -f /var/log/krb4kdc.log Jun 06 06:34:13 ipaserver01.testrelm.test krb5kdc[16265](info): TGS_REQ (8 etypes {18 17 20 19 16 23 25 26}) 10.19.34.11: ISSUE: authtime 1496744877, etypes {rep=18 tkt=18 ses=18}, HTTP/ipaserver01.testrelm.test for ldap/ipaserver01.testrelm.test Jun 06 06:34:13 ipaserver01.testrelm.test krb5kdc[16265](info): ...
