Chapter 2. Configuring Red Hat Identity management
You can configure Red Hat OpenStack Platform with federated user management with the following features:
- Red Hat Identity Management (IdM) is external to Red Hat OpenStack Platform
- Red Hat IdM is the source of all user and group information
- Red Hat Single Signon (RH-SSO) is configured to use Red Hat IdM for user Federation
2.1. Creating the IdM service account for RH-SSO
If you use anonomous binds, some information that is essential for Red Hat Single Sign-On (RH-SSO) is withheld for security reasons. As a result, you need provide the appropriate privileges for RH-SSO in the forma a dedicated account to query the IdM LDAP server for this information:
LDAP_URL="ldaps://$FED_IPA_HOST"
DIR_MGR_DN="cn=Directory Manager"
SERVICE_NAME="rhsso"
SERVICE_DN="uid=$service_name,cn=sysaccounts,cn=etc,$FED_IPA_BASE_DN"
$ ldapmodify -H "${LDAP_URL}" -x -D "${DIR_MGR_DN}" -w <_FED_IPA_ADMIN_PASSWD_> <<EOF
dn: ${SERVICE_DN}
changetype: add
objectclass: account
objectclass: simplesecurityobject
uid: ${SERVICE_NAME}
userPassword: <_FED_IPA_RHSSO_SERVICE_PASSWD_>
passwordExpirationTime: 20380119031407Z
nsIdleTimeout: 0
EOF
You can use the configure-federation script to perform the above step: $ ./configure-federation create-ipa-service-account
2.2. Creating a test user
Create a user account in IdM for testing:
Procedure
Create a user
jdoein IdM:$ipa user-add --first John --last Doe --email jdoe@example.com jdoe
Assign a password to the user:
$ipa passwd jdoe
2.3. Creating an IdM group for OpenStack users
You must have an IdM group openstack-users to map to the Keystone group federated_users. Map the test user to this group.
Create the openstack-users group in Red Hat Identity Management (IdM):
Procedure
Ensure that the
openstack-usersgroup does not exist:$ ipa group-show openstack-users ipa: ERROR: openstack-users: group not found
Add the openstack-users group to IdM:
ipa group-add openstack-users
Add the test users to the
openstack-usersgroup:ipa group-add-member --users jdoe openstack-users
Verify that the
openstack-usersgroup exists and has the test user as a member:$ ipa group-show openstack-users Group name: openstack-users GID: 331400001 Member users: jdoe
