SSSD is NOT a requirement for Federation though; you can use +any supported linux flavor. At this time, SSSD is the only Filter available +with regards to capturing IdP attributes that can be used in making advanced mapping +decisions (such as IdP group membership information). + + + +1) Install FreeIPA Server on ipa.example.com. This is achieved through running: +# yum install freeipa-server bind bind-dyndb-ldap +# ipa-server-intall + + + +2) Add a FreeIPA user called testuser: +$ kinit admin@EXAMPLE.COM +$ ipa group-add odl_users --desc "ODL Users" +$ ipa group-add odl_admin --desc "ODL Admin" +$ ipa user-add testuser --first Test --last USER --email test.user@example.com +$ ipa group-add-member odl_users --user testuser +$ ipa group-add-member odl_admin --user testuser + + + +3) Install FreeIPA Client on odl.example.com. This is achieved through running: +# yum install freeipa-client +# ipa-client-install + + + +4) Set up Client keytab for HTTP access on odl.example.com: +# ipa-getkeytab -p HTTP/odl.brcd-sssd-tb.com@BRCD-SSSD-TB.COM \ + -s freeipa.brcd-sssd-tb.com -k /etc/krb5.keytab +# chmod 644 /etc/krb5.keytab +NOTE: The second command allows Apache to read the keytab. There are more +secure methods to support such access through SELINUX, but they are outside +the scope of this tutorial. + + + +5) Install Apache on odl.example.com. This is achieved through running: +# yum install httpd + + + +6) Create an Apache application to broker federation between ODL and FreeIPA. +Create the following file on odl.example.com: + +[root@odl /]# cat /etc/httpd/conf.d/my_app.conf +<Location "/*"> + AuthType Kerberos + AuthName "Kerberos Login" + KrbMethodNegotiate On + KrbMethodK5Passwd on + KrbAuthRealms EXAMPLE.COM + Krb5KeyTab /etc/krb5.keytab + require valid-user +</Location> + + +<LocationMatch "/*"> + + RequestHeader set X-SSSD-REMOTE_USER expr=%{REMOTE_USER} + RequestHeader set X-SSSD-AUTH_TYPE expr=%{AUTH_TYPE} + RequestHeader set X-SSSD-REMOTE_HOST expr=%{REMOTE_HOST} + RequestHeader set X-SSSD-REMOTE_ADDR expr=%{REMOTE_ADDR} + LookupUserAttr mail REMOTE_USER_EMAIL + RequestHeader set X-SSSD-REMOTE_USER_EMAIL %{REMOTE_USER_EMAIL}e + LookupUserAttr givenname REMOTE_USER_FIRSTNAME + RequestHeader set X-SSSD-REMOTE_USER_FIRSTNAME %{REMOTE_USER_FIRSTNAME}e + LookupUserAttr sn REMOTE_USER_LASTNAME + RequestHeader set X-SSSD-REMOTE_USER_LASTNAME %{REMOTE_USER_LASTNAME}e + LookupUserGroups REMOTE_USER_GROUPS ":" + RequestHeader set X-SSSD-REMOTE_USER_GROUPS %{REMOTE_USER_GROUPS}e +</LocationMatch> + +ProxyPass / http://localhost:8383/ +ProxyPassReverse / http://localhost:8383/ + + + +7) Install the ODL distribution in the /opt folder on odl.example.com. + + + +8) Add a federation connector to the jetty server hosting ODL on +odl.example.com: + +[user@odl distribution]$ cat etc/jetty.xml +<?xml version="1.0"?> +<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting// +DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd"> + +<Configure class="org.eclipse.jetty.server.Server"> + + <!-- =========================================================== --> + <!-- Set connectors --> + <!-- =========================================================== --> + <!-- One of each type!
