Method Detail

invalidateToken

public Optional<Token> invalidateToken(String tokenKey)

Description copied from interface: TokenAuthenticationManager

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

Specified by:

invalidateToken in interface TokenAuthenticationManager

Parameters:

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

invalidateAllTokens

public void invalidateAllTokens()

Description copied from interface: TokenAuthenticationManager

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

Specified by:

invalidateAllTokens in interface TokenAuthenticationManager

removeExpiredTokens

public void removeExpiredTokens()

Description copied from interface: TokenAuthenticationManager

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.

Specified by:

removeExpiredTokens in interface TokenAuthenticationManager

findUserByToken

public User findUserByToken(Token token,
                            Application application)

                            OperationFailedException

Description copied from interface: TokenAuthenticationManager

Will find a user via the passed in token.

Specified by:

findUserByToken in interface TokenAuthenticationManager

Parameters:

token - the token

application - the application to do the lookup for

Returns:

the User associated to the given token

Throws:

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

OperationFailedException - if there was an issue accessing the user from the underlying directory

findUserTokenByKey

public Token findUserTokenByKey(String tokenKey,
                                Application application)

                                ApplicationAccessDeniedException,
                                OperationFailedException

Description copied from interface: TokenAuthenticationManager

Returns the token matching a given key

Specified by:

findUserTokenByKey in interface TokenAuthenticationManager

Parameters:

tokenKey - the token key

application - the application to do the lookup for

Returns:

the Token with the given token key

Throws:

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

ApplicationAccessDeniedException - the user is not allowed to authenticate with the application.

OperationFailedException - if there was an issue accessing the user from the underlying directory

findAuthorisedApplications

public List<Application> findAuthorisedApplications(User user,
                                                    String applicationName)

                                                    DirectoryNotFoundException

Description copied from interface: TokenAuthenticationManager

Returns a list of applications a user is authorised to authenticate with.

NOTE: this is a potentially expensive call, iterating all applications and all group mappings for each application and determining group membership, ie. expense = number of applications * number of group mappings per application.

Specified by:

findAuthorisedApplications in interface TokenAuthenticationManager

Parameters:

user - user to search for.

applicationName - name of the current application

Returns:

list of applications.

Description copied from interface: TokenAuthenticationManager

Authenticates an application and generates an authentication token.

Specified by:

authenticateApplication in interface TokenAuthenticationManager

Parameters:

application - the application being authenticated

                                                       throws InvalidAuthenticationException

Description copied from interface: TokenAuthenticationManager

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

                              ExpiredCredentialException

Description copied from interface: TokenAuthenticationManager

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.

Specified by:

authenticateUser in interface TokenAuthenticationManager

authenticateContext - The authentication details for the user.

tokenLifetime - Requested lifetime of the token

Returns:

The authenticated token for the user.

Throws:

InvalidAuthenticationException - The authentication was not successful.

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

InactiveAccountException - user account is inactive.

ApplicationAccessDeniedException - user does not have access to authenticate with application.

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

authenticateUserWithoutValidatingPassword

public Token authenticateUserWithoutValidatingPassword(Application application,
                                                       UserAuthenticationContext authenticateContext)
                                                throws InvalidAuthenticationException,

                                                       ApplicationAccessDeniedException

Description copied from interface: TokenAuthenticationManager

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 TokenAuthenticationManager.authenticateUser(Application, UserAuthenticationContext, TokenLifetime) method.

Specified by:

authenticateUserWithoutValidatingPassword in interface TokenAuthenticationManager

authenticateContext - The authentication details for the user.

Returns:

The authenticated token for the user.

Throws:

InvalidAuthenticationException - if the authentication was not successful.

OperationFailedException - if the error thrown by directory implementation when attempting to find or authenticate the user.

InactiveAccountException - if the user account is inactive.

ApplicationAccessDeniedException - if the user does not have access to authenticate with application.
