Error message

cannot obtain user info

What it means

KubeSphere's ModifyPassword handler returns this wrapped 500 Internal Error when the authenticated user identity cannot be extracted from the request context. The apirequest.UserFrom() helper reads the user info that Kubernetes authentication middleware is expected to inject; if absent, the handler cannot determine who is modifying the password, so it aborts with an internal error rather than proceeding unauthenticated.

Solutions

  1. Ensure the request carries a valid bearer token / cookie so authn middleware populates the user in context
  2. Verify requests go through the authenticated kapis path, not a route that skips the auth filter
  3. Check token issuer (JWT/OIDC) configuration so valid tokens are recognized and mapped to users
  4. If you are the admin, inspect middleware/authn setup (oauth server, authentication secret config) for misconfiguration

Example fix

// before: calling handler directly with bare context
req = req.WithContext(context.Background())
// after: ensure identity is present (normally via authn middleware)
req = req.WithContext(apirequest.WithUser(ctx, &user.DefaultInfo{Name: username}))
Defensive patterns

Strategy: try-catch

Validate before calling

// client: only call with an authenticated token
if token == "" { return errors.New("no bearer token; password change will fail") }

Type guard

func hasUser(ctx context.Context) bool {
  _, ok := apirequest.UserFrom(ctx)
  return ok
}

Try / catch

resp, err := client.Do(req)
if err != nil { return err }
if resp.StatusCode == http.StatusInternalServerError {
  // re-authenticate and retry with a valid token
  return errors.New("request context had no authenticated user; obtain a new token")
}

Prevention

When it happens

Trigger: A password modification request reaches ModifyPassword without a user value in the request context — typically when the request bypasses or is misconfigured for the authentication chain (missing/invalid bearer token accepted by an unauthenticated route, or authn middleware not populating context).

Common situations: Calling the API through a proxy that strips Authorization headers; tokens issued by a broken or partially configured OIDC integration; requests routed to the kapis endpoint without going through the kube-apiserver proxy/authentication; testing endpoints directly without a token.
