Authenticates an application and generates an authentication token.

Parameters:

application - the application being authenticated

authenticationContext - application authentication credentials.

tokenLifetime - Requested lifetime of the token

Returns:

generated authentication token.

Throws:

com.atlassian.crowd.exception.InvalidAuthenticationException - authentication was not successful because either the application does not exist, the password is incorrect, the application is inactive or there was a problem generating the authentication token.

authenticateApplicationWithoutValidatingPassword

com.atlassian.crowd.model.token.Token authenticateApplicationWithoutValidatingPassword(com.atlassian.crowd.model.application.Application application,
 com.atlassian.crowd.model.authentication.ApplicationAuthenticationContext authenticationContext,
 com.atlassian.crowd.model.token.TokenLifetime tokenLifetime)
                                                                                throws com.atlassian.crowd.exception.InvalidAuthenticationException

Authenticates an application and generates an authentication token, ignoring the credentials.

This method should only be used to generate a token for an application that has already authenticated via some other means (eg. TLS client certificates) as this method bypasses any password checks.

Parameters:

application - the application being authenticated

authenticationContext - application authentication credentials.

tokenLifetime - Requested lifetime of the token

Returns:

generated authentication token.

Throws:

com.atlassian.crowd.exception.InvalidAuthenticationException - authentication was not successful because either the application does not exist, the application is inactive or there was a problem generating the authentication token.

2.9

authenticateUser

com.atlassian.crowd.model.token.Token authenticateUser(com.atlassian.crowd.model.application.Application application,
 com.atlassian.crowd.model.authentication.UserAuthenticationContext authenticateContext,
 com.atlassian.crowd.model.token.TokenLifetime tokenLifetime)
                                                throws com.atlassian.crowd.exception.InvalidAuthenticationException,
com.atlassian.crowd.exception.OperationFailedException,
com.atlassian.crowd.exception.InactiveAccountException,
com.atlassian.crowd.manager.application.ApplicationAccessDeniedException,
com.atlassian.crowd.exception.ExpiredCredentialException

Authenticates a user and and generates an authentication token. The password of the user is validated before generating a token.

The RemoteDirectory.authenticate(String, com.atlassian.crowd.embedded.api.PasswordCredential) method is iteratively called for each assigned directory. If the user does not exist in one directory, the directory is skipped and the next one is examined. If the user does not exist in any of the assigned directories then an InvalidAuthenticationException is thrown.

Parameters:

application -

authenticateContext - The authentication details for the user.

tokenLifetime - Requested lifetime of the token

Returns:

The authenticated token for the user.

Throws:

com.atlassian.crowd.exception.InvalidAuthenticationException - The authentication was not successful.

com.atlassian.crowd.exception.OperationFailedException - error thrown by directory implementation when attempting to find or authenticate the user.

com.atlassian.crowd.exception.InactiveAccountException - user account is inactive.

com.atlassian.crowd.manager.application.ApplicationAccessDeniedException - user does not have access to authenticate with application.

com.atlassian.crowd.exception.ExpiredCredentialException - the user's credentials have expired. The user must change their credentials in order to successfully authenticate.

authenticateUserWithoutValidatingPassword

com.atlassian.crowd.model.token.Token authenticateUserWithoutValidatingPassword(com.atlassian.crowd.model.application.Application application,
 com.atlassian.crowd.model.authentication.UserAuthenticationContext authenticateContext)
                                                                         throws com.atlassian.crowd.exception.InvalidAuthenticationException,
com.atlassian.crowd.exception.OperationFailedException,
com.atlassian.crowd.exception.InactiveAccountException,
com.atlassian.crowd.manager.application.ApplicationAccessDeniedException

Feigns the authentication process for a user and creates a token for the authentication without validating the password.

This method should only be used to generate a token for a user that has already authenticated credentials via some other means (eg. SharePoint NTLM connector) as this method bypasses any password checks.

If you want actual password authentication, use the authenticateUser(Application, UserAuthenticationContext, TokenLifetime) method.

Parameters:

application -

authenticateContext - The authentication details for the user.

Returns:

The authenticated token for the user.

Throws:

com.atlassian.crowd.exception.InvalidAuthenticationException - if the authentication was not successful.

com.atlassian.crowd.exception.OperationFailedException - if the error was thrown by directory implementation when attempting to find or authenticate the user.

com.atlassian.crowd.exception.InactiveAccountException - if the user account is inactive.

com.atlassian.crowd.manager.application.ApplicationAccessDeniedException - if the user does not have access to authenticate with application.

 com.atlassian.crowd.model.authentication.ValidationFactor[] validationFactors)
                                                        throws com.atlassian.crowd.exception.InvalidTokenException

Validates an application token key given validation factors.

Parameters:

tokenKey - returns a valid token corresponding to the tokenKey.

validationFactors - validation factors for generating the token hash.

Returns:

validated token.

Throws:

com.atlassian.crowd.exception.InvalidTokenException - if the tokenKey or corresponding client validation factors do not represent a valid application token.

Validates a user token key given validation factors and checks that the user is allowed to authenticate with the specified application

Parameters:

application - the application performing the authentication

userTokenKey - returns a valid token corresponding to the tokenKey.

validationFactors - validation factors for generating the token hash.

Returns:

validated authentication token.

Throws:

com.atlassian.crowd.exception.InvalidTokenException - if the userTokenKey or corresponding validationFactors do not represent a valid SSO token.

com.atlassian.crowd.exception.OperationFailedException - there was an error communicating with an underlying directory when determining if a user is allowed to authenticate with the application (eg. if a user has the appropriate group memberships).

com.atlassian.crowd.manager.application.ApplicationAccessDeniedException - the user is not allowed to authenticate with the application.

invalidateToken

Optional<com.atlassian.crowd.model.token.Token> invalidateToken(String token)

Attempts to invalidate a Token based on the passed in Token key (random hash).

If the token does not exist (ie. already invalidated) this method returns Optional.empty(). If an existing token is successfully invalidated, a TokenInvalidatedEvent is fired, and the invalidated token is returned

Parameters:

token - the token key (random hash) to invalidate.

invalidateAllTokens

void invalidateAllTokens()

Invalidates all user and application tokens. This means it will also invalidate the token of the calling application.

removeExpiredTokens

void removeExpiredTokens()

Removes all tokens that have exceeded their expiry time.

NOTE: Do not call this method from the web layer, as this is wrapped in a Spring managed transaction.

findUserByToken

com.atlassian.crowd.model.user.User findUserByToken(com.atlassian.crowd.model.token.Token token,
 com.atlassian.crowd.model.application.Application application)
                                             throws com.atlassian.crowd.exception.InvalidTokenException,
com.atlassian.crowd.exception.OperationFailedException

Will find a user via the passed in token.

Parameters:

token - the token

application - the application to do the lookup for

Returns:

the User associated to the given token

Throws:

com.atlassian.crowd.exception.InvalidTokenException - if the User or Directory cannot be found that relates to the given token, or the token is associated to an Application and not a User

com.atlassian.crowd.exception.OperationFailedException - if there was an issue accessing the user from the underlying directory

findUserTokenByKey

com.atlassian.crowd.model.token.Token findUserTokenByKey(String tokenKey,
 com.atlassian.crowd.model.application.Application application)

com.atlassian.crowd.exception.OperationFailedException

Returns the token matching a given key

Parameters:

tokenKey - the token key

application - the application to do the lookup for

the Token with the given token key

Throws:

com.atlassian.crowd.exception.InvalidTokenException - if the token cannot be found by the give key, or the token is associated to an Application and not a User

com.atlassian.crowd.exception.OperationFailedException - if there was an issue accessing the user from the underlying directory

com.atlassian.crowd.manager.application.ApplicationAccessDeniedException - the user is not allowed to authenticate with the application.

user - user to search for.

applicationName - name of the current application

Returns:

list of applications.
