Modern enterprises require robust, scalable, and compliant authentication solutions. GoAuth has evolved beyond basic JWT functionality to provide comprehensive enterprise features that meet the demanding requirements of large organizations.

Enterprise Authentication Challengesโ€‹

Enterprise environments face unique challenges that go beyond simple user authentication:

  • Scale: Supporting thousands of concurrent users
  • Compliance: Meeting regulatory requirements (GDPR, SOC2, HIPAA)
  • Integration: Connecting with existing enterprise systems
  • Security: Implementing advanced security measures
  • Auditing: Comprehensive logging and monitoring
  • Multi-tenancy: Supporting multiple organizations

Single Sign-On (SSO) Integrationโ€‹

GoAuth provides robust SSO capabilities that integrate seamlessly with enterprise identity providers:

SAML 2.0 Supportโ€‹

package main

import (
"github.com/your-org/goauth"
"github.com/your-org/goauth/saml"
)

func main() {
auth := goauth.New(&goauth.Config{
SSOProvider: "saml",
SAMLConfig: &saml.Config{
IDPMetadataURL: "https://idp.company.com/metadata",
EntityID: "https://app.company.com",
ACSURL: "https://app.company.com/auth/saml/callback",
X509Cert: "path/to/cert.pem",
PrivateKey: "path/to/private.key",
},
})

// Handle SAML authentication
http.HandleFunc("/auth/saml", auth.SAMLHandler)
http.HandleFunc("/auth/saml/callback", auth.SAMLCallbackHandler)
}

OAuth 2.0 / OpenID Connectโ€‹

func configureOIDC(auth *goauth.Auth) {
oidcConfig := &goauth.OIDCConfig{
ProviderURL: "https://accounts.google.com",
ClientID: os.Getenv("GOOGLE_CLIENT_ID"),
ClientSecret: os.Getenv("GOOGLE_CLIENT_SECRET"),
RedirectURL: "https://app.company.com/auth/callback",
Scopes: []string{"openid", "email", "profile"},
AllowedDomains: []string{"company.com", "subsidiary.com"},
}

auth.ConfigureOIDC(oidcConfig)
}

LDAP/Active Directory Integrationโ€‹

For organizations with existing directory services, GoAuth provides seamless LDAP integration:

type LDAPConfig struct {
ServerURL string
BindDN string
BindPassword string
BaseDN string
UserFilter string
GroupFilter string
Attributes []string
}

func configureLDAP(auth *goauth.Auth) {
ldapConfig := &goauth.LDAPConfig{
ServerURL: "ldaps://ldap.company.com:636",
BindDN: "cn=service-account,dc=company,dc=com",
BindPassword: os.Getenv("LDAP_PASSWORD"),
BaseDN: "dc=company,dc=com",
UserFilter: "(&(objectClass=person)(sAMAccountName=%s))",
GroupFilter: "(&(objectClass=group)(member=%s))",
Attributes: []string{"cn", "mail", "memberOf", "department"},
}

auth.ConfigureLDAP(ldapConfig)
}

Multi-Factor Authentication (MFA)โ€‹

Enterprise security requires multiple layers of authentication:

TOTP (Time-based One-Time Password)โ€‹

func setupTOTP(user *User) (*goauth.TOTPConfig, error) {
config := &goauth.TOTPConfig{
Issuer: "Company App",
AccountName: user.Email,
Algorithm: "SHA1",
Digits: 6,
Period: 30,
}

secret, qrCode, err := auth.GenerateTOTPSecret(config)
if err != nil {
return nil, err
}

// Store secret securely for user
user.TOTPSecret = secret
user.TOTPEnabled = true

return &goauth.TOTPConfig{
Secret: secret,
QRCode: qrCode,
Config: config,
}, nil
}

func verifyTOTP(user *User, token string) error {
return auth.VerifyTOTP(user.TOTPSecret, token)
}

SMS/Email Verificationโ€‹

func sendVerificationCode(user *User, method string) error {
code := generateSecureCode(6)

// Store code with expiration
verification := &goauth.VerificationCode{
UserID: user.ID,
Code: code,
Method: method,
ExpiresAt: time.Now().Add(time.Minute * 10),
}

if err := storeVerificationCode(verification); err != nil {
return err
}

// Send via appropriate method
switch method {
case "sms":
return sendSMSCode(user.Phone, code)
case "email":
return sendEmailCode(user.Email, code)
default:
return fmt.Errorf("unsupported verification method: %s", method)
}
}

Role-Based Access Control (RBAC)โ€‹

Enterprise applications require sophisticated permission management:

type Role struct {
ID string `json:"id"`
Name string `json:"name"`
Description string `json:"description"`
Permissions []Permission `json:"permissions"`
Metadata map[string]string `json:"metadata"`
}

type Permission struct {
Resource string `json:"resource"`
Actions []string `json:"actions"`
Scope string `json:"scope"` // global, organization, team, user
}

func checkPermission(user *User, resource, action string) bool {
for _, role := range user.Roles {
for _, permission := range role.Permissions {
if permission.Resource == resource {
for _, allowedAction := range permission.Actions {
if allowedAction == action || allowedAction == "*" {
return true
}
}
}
}
}
return false
}

Compliance and Auditingโ€‹

Enterprise applications must meet strict compliance requirements:

Comprehensive Loggingโ€‹

type AuditLog struct {
ID string `json:"id"`
Timestamp time.Time `json:"timestamp"`
UserID string `json:"user_id"`
Action string `json:"action"`
Resource string `json:"resource"`

IPAddress string `json:"ip_address"`
UserAgent string `json:"user_agent"`
Metadata map[string]interface{} `json:"metadata"`
Success bool `json:"success"`
Error string `json:"error,omitempty"`
}

func logAuditEvent(event *AuditLog) error {
// Ensure compliance with retention policies
if err := validateRetentionPolicy(event); err != nil {
return err
}

// Store in secure, tamper-evident storage
if err := storeAuditLog(event); err != nil {
return err
}

// Send to SIEM systems if configured
if siemEnabled {
go sendToSIEM(event)
}

return nil
}

type RetentionPolicy struct {
DataType string `json:"data_type"`
Retention time.Duration `json:"retention"`
AutoDelete bool `json:"auto_delete"`
LegalHold bool `json:"legal_hold"`

}

func enforceRetentionPolicies() {
ticker := time.NewTicker(time.Hour * 24) // Daily
defer ticker.Stop()

for range ticker.C {
policies := getRetentionPolicies()

for _, policy := range policies {
if policy.AutoDelete && !policy.LegalHold {
deleteExpiredData(policy)
}
}
}
}

Multi-Tenancy Supportโ€‹

Enterprise applications often serve multiple organizations:

type Tenant struct {
ID string `json:"id"`
Name string `json:"name"`
Domain string `json:"domain"`
Settings map[string]string `json:"settings"`
Features []string `json:"features"`
Quotas map[string]int `json:"quotas"`
CreatedAt time.Time `json:"created_at"`
Status string `json:"status"`
}

func getTenantFromRequest(r *http.Request) (*Tenant, error) {
// Extract tenant from subdomain
host := r.Host
subdomain := strings.Split(host, ".")[0]

// Or from custom header
tenantID := r.Header.Get("X-Tenant-ID")

if tenantID == "" {
tenantID = subdomain
}

return getTenantByID(tenantID)
}

func applyTenantContext(ctx context.Context, tenant *Tenant) context.Context {
return context.WithValue(ctx, "tenant", tenant)
}

High Availability and Scalingโ€‹

Enterprise applications require 99.9%+ uptime:

}

func setupHighAvailability() {
// Health check all nodes
go healthCheckNodes()

// Setup automatic failover
go monitorClusterHealth()

// Configure session replication
setupSessionReplication()
}

Database Sharding and Replicationโ€‹

type DatabaseConfig struct {
Primary string `json:"primary"`
Replicas []string `json:"replicas"`
Shards []string `json:"shards"`
Strategy string `json:"strategy"`
}

func setupDatabaseCluster(config *DatabaseConfig) {
// Setup read replicas
for _, replica := range config.Replicas {
setupReadReplica(replica)
}

// Setup sharding
if len(config.Shards) > 0 {
setupSharding(config.Shards, config.Strategy)
}

// Setup automatic failover
setupDatabaseFailover(config.Primary, config.Replicas)
}

Security Hardeningโ€‹

func setupSecurityMiddleware(config *SecurityConfig) {
// Rate limiting
limiter := rate.NewLimiter(rate.Every(time.Second), config.RateLimitPerIP)

// IP filtering
ipFilter := createIPFilter(config.IPWhitelist, config.IPBlacklist)

// Brute force protection
bruteForceProtection := createBruteForceProtection(config.MaxLoginAttempts, config.LockoutDuration)

// Apply middleware
http.HandleFunc("/auth/", applySecurityMiddleware(
authHandler,

ipFilter,
bruteForceProtection,
))
}

Encryption at Rest and in Transitโ€‹

type EncryptionConfig struct {
Algorithm string `json:"algorithm"`

setupHSMEncryption(config)
} else {
setupSoftwareEncryption(config)
}

// Setup automatic key rotation
if config.KeyRotation {
go scheduleKeyRotation(config)
}

// Encrypt sensitive data
setupDataEncryption(config)
}

Monitoring and Alertingโ€‹

Enterprise applications require comprehensive monitoring:

type MonitoringConfig struct {
MetricsEndpoint string `json:"metrics_endpoint"`
HealthChecks []string `json:"health_checks"`
AlertingRules []AlertingRule `json:"alerting_rules"`
Dashboards []string `json:"dashboards"`
}

func setupMonitoring(config *MonitoringConfig) {
// Expose metrics for Prometheus
http.HandleFunc("/metrics", promhttp.Handler())

// Setup health checks
for _, check := range config.HealthChecks {
setupHealthCheck(check)
}

// Setup alerting
for _, rule := range config.AlertingRules {
setupAlertingRule(rule)
}

// Setup dashboards
setupDashboards(config.Dashboards)
}
