Talend Data Catalog is able to support three authentication methods.
| Authentication method | Description |
|---|---|
| Native | where the password is managed by the software and stored within the database. |
| LDAP | where the software does not manage or store the LDAP passwords at all. Instead, it is simply passed it through to LDAP in order to authenticate. |
| External | such as Single Sign On (SSO), where the software does not perform any authentication, and leaves that responsibility to a local Single Sign On service managed by the customer. |
- Mixed Native and LDAP authentications where users may be authenticated either as native or LDAP users.
- External authentication where the system does not perform any authentication, leaving it up to a local Single Sign On environment.
