## What it is
Cloud Foundry's User Account and Authentication (UAA) server, a multi-tenant identity management service that acts as an OAuth2 provider and OpenID Connect-certified identity server. It issues tokens, manages user accounts and OAuth2 clients, and can serve as an SSO service, either within Cloud Foundry or standalone.

## Use cases
- run a standalone oauth2 authorization server
- add single sign-on to my applications
- issue and validate access tokens for microservices
- manage user accounts with SCIM provisioning
- integrate LDAP authentication with an identity provider
- get an openid connect certified identity server
- act as an oidc proxy in front of other identity providers

## When to choose
- you need a battle-tested, OpenID-certified OAuth2/OIDC server
- you are deploying Cloud Foundry or need CF-compatible identity management
- you need multi-tenancy, SCIM user provisioning, or LDAP integration out of the box

## When to avoid
- you want a lightweight embedded auth library rather than a separate server
- your stack is not JVM-based and you cannot operate a Java/Tomcat service
- you need full OpenID Connect feature coverage beyond UAA's partial OIDC support
