## What it is
TOPIAM is an open-source IAM/IDaaS identity and access management platform for centrally managing employee accounts, permissions, authentication, and application access. It supports SAML2, OAuth2, OIDC, CAS, and JWT for single sign-on, integrates identity sources like DingTalk, WeCom, Feishu, LDAP, and AD, and provides MFA, audit logging, and SCIM 2.0 provisioning.

## Use cases
- implement single sign-on across internal and SaaS applications
- centralize employee account and permission management
- sync users from DingTalk, WeCom, Feishu, LDAP, or Active Directory
- add multi-factor authentication to enterprise apps
- act as a SAML2 or OIDC identity provider
- audit user access and detect anomalous logins
- automate account lifecycle on joiner/mover/leaver events

## When to choose
- you need a self-hosted, open-source IAM/SSO platform supporting SAML2, OIDC, OAuth2, and CAS
- your organization uses Chinese identity sources like DingTalk, WeCom, or Feishu
- you need MFA, password policies, and behavioral auditing out of the box
- you require domestic-crypto (SM algorithms) and xinchuang compatibility

## When to avoid
- you need a lightweight embedded auth library rather than a full platform
- your stack is not Java/JVM-based and you cannot run a separate identity service
- you require a permissive license - it is AGPL-3.0
- you need cloud-native IAM with managed hosting
