A developer has multiple LDAP Authentication providers. The user is not required to pass the authentication test of the Authentication provider
* If authentication succeeds, control is returned to the caller; no subsequent Authentication provider down the list Is executed.
* If authentication fails, authentication continues down the list of providers.
What should be the JAAS Control flag value in Apache Jackrabbit Oak External Login Module configuration?
The JAAS Control flag SUFFICIENT is used when you have multiple LDAP authentication providers and you want the following behavior:
Immediate Return on Success:
If authentication succeeds with the current provider, control is returned to the caller immediately, and no subsequent providers in the list are executed.
This is efficient and reduces unnecessary processing if a user's credentials are successfully authenticated by one of the initial providers.
Continue on Failure:
If authentication fails with the current provider, the authentication process continues down the list of providers until a successful authentication occurs or all providers are exhausted.
This ensures that all available providers are tried before authentication is ultimately denied.
The SUFFICIENT control flag is thus well-suited for configurations where multiple authentication providers are used, and only one successful authentication is needed to grant access.
