AuthenticationStatus

java.lang.Object
- java.lang.Enum<AuthenticationStatus>
- - jakarta.security.enterprise.AuthenticationStatus

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<AuthenticationStatus>
```
public enum AuthenticationStatus
extends java.lang.Enum<AuthenticationStatus>
```
The AuthenticationStatus is used as a return value by primarily the HttpAuthenticationMechanism to indicate the result (status) of the authentication process.
For the result from HttpAuthenticationMechanism.validateRequest(jakarta.servlet.http.HttpServletRequest, jakarta.servlet.http.HttpServletResponse, jakarta.security.enterprise.authentication.mechanism.http.HttpMessageContext) an AuthenticationStatus must be transformed by the Jakarta EE server into the corresponding Jakarta Authentication AuthStatus according to the following rules:
- AuthenticationStatus.NOT_DONE to AuthStatus.SUCCESS
- AuthenticationStatus.SEND_CONTINUE to AuthStatus.SEND_CONTINUE
- AuthenticationStatus.SUCCESS to AuthStatus.SUCCESS
- AuthenticationStatus.SEND_FAILURE to AuthStatus.SEND_FAILURE
After the transformation as outlined above the transformed result has to be processed by the Jakarta EE server as specified by the Servlet Container Profile of the Jakarta Authentication spec.
Implementation note: while the Jakarta Authentication Servlet Container Profile is the authoritative source on how to process the AuthStatus.SUCCESS result and this specification puts no constraints of any kind on that, the expectation is that Jakarta EE servers in practice will mainly look at the result being AuthStatus.SUCCESS or not AuthStatus.SUCCESS. Simply said, if the result is AuthStatus.SUCCESS the authenticated identity (if any) must be set (established) for the current HTTP request, otherwise not.
The return value of SecurityContext.authenticate(jakarta.servlet.http.HttpServletRequest, jakarta.servlet.http.HttpServletResponse, jakarta.security.enterprise.authentication.mechanism.http.AuthenticationParameters) , which is also of type AuthenticationStatus, strongly relates to the outcome of the HttpAuthenticationMechanism#validateRequest method as described above, but must be transformed by the Jakarta EE server from the corresponding outcome of the HttpServletRequest.authenticate(jakarta.servlet.http.HttpServletResponse) call as follows:
- true to AuthenticationStatus.SUCCESS
- false to [last status] (see below)
- ServletException or IOException to AuthenticationStatus.SEND_FAILURE
When an HttpAuthenticationMechanism was used [last status] must be the value returned by HttpAuthenticationMechanism#validateRequest.
When a Jakarta Authentication ServerAuthModule (SAM) was used and an HttpAuthenticationMechanism was not used Jakarta EE servers are encouraged, but not required, to set [last status] to the value returned by ServerAuthModule#validateRequest transformed as follows:
- AuthStatus.SEND_CONTINUE to AuthenticationStatus.SEND_CONTINUE
- AuthStatus.SUCCESS to AuthenticationStatus.SUCCESS
- AuthStatus.SEND_FAILURE to AuthenticationStatus.SEND_FAILURE
- (all other outcomes) to AuthenticationStatus.NOT_DONE
When a Jakarta EE Server proprietary identity store equivalent was used and an HttpAuthenticationMechanism was not used Jakarta EE servers are encouraged, but not required, to set [last status] to a value that logically corresponds to the description of each enum constant of AuthenticationStatus. This outcome should never be depended on by application code as being portable.
Application code calling SecurityContext#authenticate is expected to act on all possible values of AuthenticationStatus.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`NOT_DONE` The authentication mechanism was called, but decided not to authenticate.
`SEND_CONTINUE` The authentication mechanism was called and a multi-step authentication dialog with the caller has been started (for instance, the caller has been redirected to a login page).
`SEND_FAILURE` The authentication mechanism was called but the caller was not successfully authenticated and therefore the caller principal will not be made available.
`SUCCESS` The authentication mechanism was called and the caller was successfully authenticated.

- Enum Constant Detail
  - NOT_DONE
```
public static final AuthenticationStatus NOT_DONE
```
    The authentication mechanism was called, but decided not to authenticate. This status would be typically returned in pre-emptive security; the authentication mechanism is called, but authentication is optional and would only take place when for instance a specific request header is present.
  - SEND_CONTINUE
```
public static final AuthenticationStatus SEND_CONTINUE
```
    The authentication mechanism was called and a multi-step authentication dialog with the caller has been started (for instance, the caller has been redirected to a login page). Simply said authentication is "in progress". Calling application code (if any) should not write to the response when this status is received.
  - SUCCESS
```
public static final AuthenticationStatus SUCCESS
```
    The authentication mechanism was called and the caller was successfully authenticated. After the Jakarta EE server has processed this outcome, the caller principal is available.
  - SEND_FAILURE
```
public static final AuthenticationStatus SEND_FAILURE
```
    The authentication mechanism was called but the caller was not successfully authenticated and therefore the caller principal will not be made available.
    Note that this status should be used to indicate a logical problem (such as a credential not matching or a caller ID that can not be found). Exceptions should be used for system level problems (such as a database connection timing out).

  - values
```
public static AuthenticationStatus[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (AuthenticationStatus c : AuthenticationStatus.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static AuthenticationStatus valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
