Hi, I would like to use Keycloak as SSO provider fo Nextcloud 18.
I followed the instructions: https://devopstales.github.io/sso/nextcloud-sso/
I have installed Social Login app https://apps.nextcloud.com/apps/sociallogin
I do not want to auto-create users in nextcloud after they login using SSO. I just want to allow existing Nextcloud users to login via SSO using OpenID connect protocol.
Users in Keycloak and Nextcloud have the same login name and email. I also want to solve permissions and user groups in Nextcloud, not map it from Keycloak.
In social login app I have checked “Disable auto create new users”.
After I try to login using keycloak, I got following error: “Auto creating new users is disabled” and login fails. But user with the same login name exists in Nextcloud and Keycloak.
I need to keep the possibility of logging in with the local Nexcloud account without using SSO.
What I do bad?
Is it necessary to set Mappers in Keycloak client? But how? I tried everything possible, but still without success.
I think I need to set up login and email mapping.
Thanks for help.
