com.atlassian.crowd.integration.http.CachedCrowdHttpAuthenticatorImpl

All Implemented Interfaces:

CrowdHttpAuthenticator

public class CachedCrowdHttpAuthenticatorImpl
extends Object

Similar to CrowdHttpAuthenticatorImpl, but uses additional cache layer to prevent hitting Crowd server again and again in case of negative authentication check in * checkAuthenticated(HttpServletRequest, HttpServletResponse)

Since:

6.0.11

Method Details

checkAuthenticated

@Nonnull
public AuthenticationState checkAuthenticated(jakarta.servlet.http.HttpServletRequest request,
 jakarta.servlet.http.HttpServletResponse response)
                                       throws OperationFailedException

Description copied from interface: CrowdHttpAuthenticator

Tests whether a request is authenticated via SSO. This only tests against the Crowd server if the validation interval is exceeded, this value is obtained from crowd.properties AND that there is a valid token present for the user in the Crowd Cookie. The last validated date/time attribute of the request session is updated.

Parameters:

request - HttpServletRequest

response - HttpServletResponse

Returns:

details of whether the request is authenticated

Throws:

OperationFailedException - if the operation has failed for an unknown reason.

getUser

public User getUser(jakarta.servlet.http.HttpServletRequest request)
             throws InvalidTokenException,
ApplicationPermissionException,
InvalidAuthenticationException,
OperationFailedException

Description copied from interface: CrowdHttpAuthenticator

Attempts to retrieve the currently authenticated User from the request. This will attempt to find the Crowd SSO token via:

1. a request attribute (not the request parameter), OR
2. a cookie on the request

Specified by:

getUser in interface CrowdHttpAuthenticator

Parameters:

request - HTTP request, possibly containing a Crowd SSO cookie.

Returns:

authenticated User or null if the there is no authenticated user.

Throws:

InvalidTokenException - if the token in the request is not valid.

ApplicationPermissionException - if the application is not permitted to perform the requested operation on the server.

InvalidAuthenticationException - if the application and password are not valid.

OperationFailedException - if the operation has failed for an unknown reason.

authenticate

public User authenticate(jakarta.servlet.http.HttpServletRequest request,
 jakarta.servlet.http.HttpServletResponse response,
 String username,
 String password)
                  throws InvalidTokenException,
ApplicationAccessDeniedException,
ExpiredCredentialException,
InactiveAccountException,
ApplicationPermissionException,
InvalidAuthenticationException,
OperationFailedException

Description copied from interface: CrowdHttpAuthenticator

Authenticates the user based on provided credentials.

Validation factors (such as IP address) are extracted from the request.

If the user is successfully authenticated, the Crowd SSO token is placed in:

1. the request: as an attribute, so the user is authenticated for the span of the request.
2. the response: as a cookie, so the user is authenticated for subsequent requests.

If the credentials fail authentication, any existing Crowd SSO token is removed from:

1. the request attribute.
2. the response as a cookie as a cookie with a max-age of 0.

Specified by:

authenticate in interface CrowdHttpAuthenticator

Parameters:

request - request to set the Crowd SSO token

response - response to set the Crowd SSO token cookie

username - username to authenticate

password - password of the user

Returns:

the authenticated user if the authentication was successful, otherwise an exception is thrown.

Throws:

ApplicationPermissionException - if the application is not permitted to perform the requested operation on the server.

InvalidAuthenticationException - if the application and password are not valid.

OperationFailedException - if the operation has failed for an unknown reason.
