Re: [keycloak-user] group mapper per client

Hello everyone, So, thankfully, after some careful reading, I managed to solve the first issue regarding clientSession.client.clientId, which in fact shoud be authenticationSession.client.clientId (there was a mention on using loginSession.client.clientId in place of clientSession.client.clientId on this link https://issues.jboss.org/browse/KEYCLOAK-4505, which I tried to use, without success).

If the user is not a member, then it'll display an error like "Invalid username or password". Is it possible to modify the response in such cases, stating that the account is not a member of required groups, or at least have it like "Invalid group membership". Looking forward to hearing from you!

If the user tries to authenticate against the client without being a member of the corresponding group, the authenticator should deny login. If there is no such correspondence (e.g. the client is named "foo", and the group is "AD_group_bar"), you still have the following options: - map AD groups to Keycloak roles using role-ldap-mapper, then use your adapter's configuration to restrict access only to the users with this role (e.g. <security-constraint> in web.xml); - or map AD groups to Keycloak groups, enable authorization services and use group policy (if your client adapter supports authorization, of course). This, however, will need to be configured per each client, on the contrary to the first approach (configured once per realm).

After creating the LDAP connection (read-only) and some LDAP mappers, I am trying to figure out a way how to allow login to clients for users in respective groups in AD, for example for client app1 allow login to users that are members of AD_group_app1; if account is not a member of the app1 group in AD, then he should not be allowed to login. Is it also possible to do it via role mappings? Please note that we'd like to avoid modification of AD at all costs. > > > Thanks in advance, > Ronald > _______________________________________________ > keycloak-user mailing list > keycloak-user(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/keycloak-user
