PowerVC supports two different types of backend for authentication.
- Local OS (default)
- LDAP server
For local OS backend, PowerVC supports only the configuration where the OS users and groups are created in the default local registry (and not where the OS is configured to authenticate through LDAP server or any external PAM modules).
For both types of supported backend, PowerVC does not manage user or group information or credentials and merely routes the login request to the configured backend for authentication. Thus, policies like password expiry, length, etc. must be configured at the backend layer as PowerVC does not manage these policies.
