OpenVPN now requires BOTH a valid client certificate AND a
username/password to establish a VPN connection.
Architecture:
Client .ovpn has 'auth-user-pass' → prompts for credentials
Server.conf has 'auth-user-pass-verify verify.sh via-env'
verify.sh (bash+curl) calls POST /api/vpn/verify on the manager
Manager verifies bcrypt hash via Go's golang.org/x/crypto/bcrypt
Endpoint is localhost-only (127.0.0.1) for security
Model changes:
Instance: new AuthMode field ('cert' | 'cert+password', default cert+password)
VPNUser: new PasswordHash (bcrypt) + Password (plaintext, transient)
Backend:
model: AuthMode type, VPNUser.PasswordHash, VPNUser.Password (transient)
store: ListUsers clears PasswordHash before returning
service: CreateUser hashes password with bcrypt, enforces min 4 chars
service: ResetVPNPassword for admin password reset
service: UpdateUser preserves PasswordHash from old record
service: CreateInstance defaults AuthMode=cert+password
api: POST /api/vpn/verify (no JWT, localhost-only, bcrypt verify)
api: POST /instances/:id/users/:uid/password (admin reset VPN pwd)
openvpn: WriteVerifyScript generates bash+curl verify script
openvpn: WriteServerConf adds script-security/auth-user-pass-verify
openvpn: GenerateClientOVPN adds auth-user-pass directive
Frontend:
Users.vue: password field on create form
Users.vue: '重置密码' button in table + dialog
Users.vue: '证书+密码' tag in auth column
api: Inst.resetVPNPassword() method
Security:
/api/vpn/verify rejects non-127.0.0.1 clients (403)
PasswordHash never exposed via any API response
verify.sh uses localhost curl (no external dependencies)
bcrypt cost=10 (same as admin passwords)
Verified: correct pwd → 200, wrong pwd → 401, missing user → 401,
non-localhost → 403, .ovpn has auth-user-pass, server.conf has
script-security 2 + auth-user-pass-verify + verify-client-cert require.
