Hi all,
I'm having some troubles integrating Keystone with Keycloak - pulling username and email from Keycloak using OIDC to Keystone works fine, but pulling groups (list of groups) doesn't. Keycloak provides such data in userinfo (pulled from Google, mapped in Keycloak and added to user): "usergroups": [ "group-a", "group-b", ], Keystone seems to be getting group names, but incorrectly parsing (?) it to a string with commas (instead of semicolon as it's required for multiple group entries to work: https://docs.openstack.org/keystone/latest/admin/federation/mapping_combinat...): 2023-12-13 08:22:13.399 1076680 DEBUG keystone.federation.utils [None req-e8b8519a-c639-450e-b4e7-ca2ea8a0f3bc -

My current setup: Google (user and groups membership) OIDC -> Keycloak OIDC -> Keystone
Mapping rules (without parameters related to group settings works fine): [ { "local": [ { "user": { "name": "{0}", "email": "{1}", "domain": { "id": "default" } } }, { "group": { "name": "{2}", "domain": { "id": "default" } } } ], "remote": [ { "type": "OIDC-preferred_username" }, { "type": "OIDC-email" }, { "type": "OIDC-usergroups" } ] } ]
