It seems likely that setting up Microsoft SSO in Phoenix requires specific environment variables. For the `PHOENIX_OAUTH2_MICROSOFT_ENTRA_ID_OIDC_CONFIG_URL`, you should use the well-known configuration endpoint provided by Microsoft Entra ID, which is typically in the format `https://login.microsoftonline.com/{tenant}/v2.0/.well-known/openid-configuration`. This URL provides the necessary metadata for OpenID Connect.
Regarding the redirect URI, it seems that you should use a format like `<origin-url> /oauth2/microsoft_entra_id/tokens`, where `<origin-url> ` is the URL where you will access Phoenix in the browser. If you have configured a root path via the `PHOENIX_HOST_ROOT_PATH` environment variable, your redirect URI should include this path, such as `<origin-url> /<root-path> /oauth2/microsoft_entra_id/tokens` (<https://docs.arize.com/phoenix/deployment/authentication#%3ARcsd9uu8qfkvfa%3A|source>).
Would you like more detailed guidance on setting up these configurations?
