Direct Known Subclasses:

HudsonPrivateSecurityRealm

public abstract class AbstractPasswordBasedSecurityRealm
extends SecurityRealm

Partial implementation of SecurityRealm for username/password based authentication. This is a convenience base class if all you are trying to do is to check the given username and password with the information stored in somewhere else, and you don't want to do anything with Spring Security.

This SecurityRealm uses the standard login form (and a few other optional mechanisms like BASIC auth) to gather the username/password information. Subtypes are responsible for authenticating this information.

Method Detail

createSecurityComponents

public SecurityRealm.SecurityComponents createSecurityComponents()

Description copied from class: SecurityRealm

Creates fully-configured AuthenticationManager that performs authentication against the user realm. The implementation hides how such authentication manager is configured.

AuthenticationManager instantiation often depends on the user-specified parameters (for example, if the authentication is based on LDAP, the user needs to specify the host name of the LDAP server.) Such configuration is expected to be presented to the user via config.jelly and then captured as instance variables inside the SecurityRealm implementation.

Your SecurityRealm may also wants to alter Filter set up by overriding SecurityRealm.createFilter(FilterConfig).

authenticate2

protected org.springframework.security.core.userdetails.UserDetails authenticate2(String username,
                                                                                  String password)
                                                                           throws org.springframework.security.core.AuthenticationException

Authenticate a login attempt. This method is the heart of a AbstractPasswordBasedSecurityRealm.

If the user name and the password pair matches, retrieve the information about this user and return it as a UserDetails object. User is a convenient implementation to use, but if your backend offers additional data, you may want to use your own subtype so that the rest of Hudson can use those additional information (such as e-mail address --- see MailAddressResolver.)

Properties like UserDetails.getPassword() make no sense, so just return an empty value from it. The only information that you need to pay real attention is UserDetails.getAuthorities(), which is a list of roles/groups that the user is in. At minimum, this must contain SecurityRealm.AUTHENTICATED_AUTHORITY (which indicates that this user is authenticated and not anonymous), but if your backend supports a notion of groups, you should make sure that the authorities contain one entry per one group. This enables users to control authorization based on groups.

If the user name and the password pair doesn't match, throw AuthenticationException to reject the login attempt.

Throws:

org.springframework.security.core.AuthenticationException

authenticate

@Deprecated
protected UserDetails authenticate(String username,
                                               String password)
                                        throws AuthenticationException

Deprecated. use authenticate2(java.lang.String, java.lang.String)

Throws:

AuthenticationException

loadUserByUsername2

public org.springframework.security.core.userdetails.UserDetails loadUserByUsername2(String username)
                                                                              throws org.springframework.security.core.userdetails.UsernameNotFoundException

Retrieves information about an user by its name.

This method is used, for example, to validate if the given token is a valid user name when the user is configuring an ACL. This is an optional method that improves the user experience. If your backend doesn't support a query like this, just always throw UsernameNotFoundException.

Overrides:

loadUserByUsername2 in class SecurityRealm

Returns:

never null.

Throws:

UserMayOrMayNotExistException2 - If the security realm cannot even tell if the user exists or not.

org.springframework.security.core.userdetails.UsernameNotFoundException

loadUserByUsername

@Deprecated
public UserDetails loadUserByUsername(String username)
                                           throws UsernameNotFoundException,
                                                  DataAccessException

Deprecated. use loadUserByUsername2(java.lang.String)

Overrides:

loadUserByUsername in class SecurityRealm

Throws:

UsernameNotFoundException

DataAccessException

loadGroupByGroupname2

public GroupDetails loadGroupByGroupname2(String groupname,
                                          boolean fetchMembers)
                                   throws org.springframework.security.core.userdetails.UsernameNotFoundException

Retrieves information about a group by its name. This method is the group version of the loadUserByUsername2(String).

Overrides:

loadGroupByGroupname2 in class SecurityRealm

Parameters:

groupname - the name of the group to fetch

fetchMembers - if true then try and fetch the members of the group if it exists. Trying does not imply that the members will be fetched and GroupDetails.getMembers() may still return null

Throws:

UserMayOrMayNotExistException2 - if no conclusive result could be determined regarding the group existence.

org.springframework.security.core.userdetails.UsernameNotFoundException - if the group does not exist.

loadGroupByGroupname

@Deprecated
public GroupDetails loadGroupByGroupname(String groupname)
                                              throws UsernameNotFoundException,
                                                     DataAccessException

Deprecated. use loadGroupByGroupname2(java.lang.String, boolean)

Throws:

UsernameNotFoundException
