User Migration Considerations for OAuth2 Authentication in Nextcloud
A Nextcloud user explores migrating to an OAuth2 authentication provider while preserving existing user accounts and data.
A user is investigating the process of switching a Nextcloud instance to utilize an external OAuth2 authentication provider instead of the default local authentication method. The goal is to maintain existing user accounts and data during the transition, focusing solely on altering the authentication process itself.
A key consideration for a seamless migration is how Nextcloud identifies users when using OAuth2. The user is seeking clarification on whether user identification relies solely on aliases, similar to local authentication, or if additional data fields are employed.
A straightforward, one-to-one correspondence between user aliases on the new authentication server and those within the Nextcloud instance would facilitate a simple migration. Otherwise, a mapping or alteration of user identifiers would be necessary to ensure a successful transition.
