Ok, here’s a full report:
I created a user called “biding”. I then created a role so that this user could add other users and could be used on Keycloak for binding and adding users.
I gave it the following default roles:
- User administration
- helpdesk
- Keycloak biding (sorry for the typo)
The last one is like this:
✘ ⚡ root@freeipa /home/francis ipa privilege-show
Privilege name: Keycloak admin
Privilege name: Keycloak admin
Permissions: System: Add Users, System: Change User password
Granting privilege to roles: Keycloak biding
⚡ root@freeipa /home/francis ipa role-show
Role name: Keycloak biding
Role name: Keycloak biding
Member users: biding
Privileges: User Administrators, Group Administrators, Stage User Administrators, Stage User Provisioning,
Modify Users and Reset passwords, Modify Group membership, Keycloak admin
I can’t add a user with it on Keyclok. This is what I get on the logs:
{ "date": "[19\/Jul\/2024:14:31:59.636888234 +0200] ", "utc_time": "1721392319.636888234", "event": "AUTHZ_ERROR", "dn": "uid=biding,cn=users,cn=accounts,dc=ipa,dc=med-lo", "bind_method": "SIMPLE", "root_dn": false, "client_ip": "10.10.210.152", "server_ip": "10.10.40.20", "ldap_version": 3, "conn_id": 3722, "op_id": 1, "msg": "target_dn=(uid=testing2,cn=users,cn=accounts,dc=ipa,dc=med-lo)” }
I then added “biding” to the “admins” group.
I could then create users on keycloak with it. This is how a user looks like:
testing, users, accounts, ipa.med-lo
dn: uid=testing,cn=users,cn=accounts,dc=ipa,dc=med-lo
sn: TEst
givenName: Test
mail: testing@med-lo.eu
cn: Test TEst
uid: testing
objectClass: top
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
objectClass: postfixMailBox
objectClass: ipaobject
ipaUniqueID: b203edc0-45c9-11ef-bb0c-00505695d7f7
But, when searching for this user with my read-only system account, it doesn’t get it:
ldapsearch -b dc=ipa,dc=med-lo -D uid=system,cn=sysaccounts,cn=etc,dc=ipa,dc=med-lo -W uid=testing
Enter LDAP Password:
# extended LDIF
#
# LDAPv3
# base <dc=ipa,dc=med-lo> with scope subtree
# filter: uid=testing
# requesting: ALL
#
# search result
search: 2
result: 0 Success
# numResponses: 1
So I have two problems:
How to give “biding” permission to add and modify users without adding it to the “admins” group, and how to make the users created by it readable like a normal ipa-user?
IPA assumes that it manages posix users, i.e. users with posixaccount objectclass. Most of the ACIs are written with this assumption (targetfilter = "(objectclass=posixaccount)").
If you create your users with this objectclass I believe user management will be easier and you can rely on the existing role "User Administrator".
flo
I tried that today. The problem is that if the user is created by Keycloak, than I need to send all the attributes a posixAccount requires, such as uidNumber and gidNumber. Keycloak can’t create those by default, which makes it a bit harder to delegate user creation to Keycloak.
Any tips on a possible workaround?
Best,
Francis
