Hi,
So to be clear, what you did was spin up a new gluu server CE instance, spin up a nextcloud instance, enabled the gluu plugin for nextcloud, registered it as a client with gluu server, then created a user, logged out the local user, then logged in with the newly created gluu federated identity. Is that correct?
You must then give that new federated identity the role of 'admin' in nextcloud. Then, once that new user is an admin, try enabling or adding an app. Changing something within the admin console of nextcloud. It(nextcloud) will prompt you to enter your password.
What i am finding is that from this scenario, that nextcloud password prompt is not authenticating me with my Gluu created users' password. Meaning, the password that i used to authenticate into Nextcloud with is not being accepted at the admin console password prompt when a change is made.
