     - `enable_web_admin`, boolean. Set to `false` to disable the built-in web admin for this binding. You also need to define `templates_path` and `static_files_path` to use the built-in web admin interface. Default `true`.
     - `enable_web_client`, boolean. Set to `false` to disable the built-in web client for this binding. You also need to define `templates_path` and `static_files_path` to use the built-in web client interface. Default `true`.
+    - `enabled_login_methods`, integer. Defines the login methods available for the WebAdmin and WebClient UIs. `0` means any configured method: username/password login form and OIDC, if enabled. `1` means OIDC for the WebAdmin UI. The username/password login form will not be available for the WebAdmin UI. `2` means OIDC for the WebClient UI. The username/password login form will not be available for the WebClient UI. You can combine the values. For example `3` means that you can only login using OIDC on both WebClient and WebAdmin UI. Default: `0`.
     - `enable_https`, boolean. Set to `true` and provide both a certificate and a key file to enable HTTPS connection for this binding. Default `false`.
     - `certificate_file`, string. Binding specific TLS certificate. This can be an absolute path or a path relative to the config dir.
     - `certificate_key_file`, string. Binding specific private key matching the above certificate. This can be an absolute path or a path relative to the config dir. If not set the global ones will be used, if any.
