Configure external connections

1 minute read

API Gateway can leverage your existing identity management infrastructure and avoid maintaining separate silos of user information. For example, if you already have a database full of user credentials, API Gateway can authenticate requests against this database, rather than using its own internal user store. Similarly, API Gateway can authorize users, look up user attributes, and validate certificates against third-party identity management servers.

You can add each connection to an external system as a global External Connection in Policy Studio so that it can be reused across all filters and policies. For example, if you create a policy that authenticates users against an LDAP directory and then validates an XML signature by retrieving a public key from the same LDAP directory, it makes sense to create a global external connection for that LDAP directory. You can then select the LDAP connection in both the authentication and XML signature verification filters, rather than having to reconfigure it in both filters.
