validate

public UserModel validate(RealmModel realm,
 UserModel local)

Description copied from interface: ImportedUserValidation

If this method returns null, then the user in local storage will be removed

Specified by:

validate in interface ImportedUserValidation

Returns:

null if user no longer valid

proxy

protected UserModel proxy(RealmModel realm,
 UserModel local,
 LDAPObject ldapObject,
 boolean newUser)

supportsCredentialAuthenticationFor

public boolean supportsCredentialAuthenticationFor(String type)

Specified by:

supportsCredentialAuthenticationFor in interface CredentialAuthentication

searchForUserByUserAttributeStream

public Stream<UserModel> searchForUserByUserAttributeStream(RealmModel realm,
 String attrName,
 String attrValue)

Description copied from interface: UserQueryMethodsProvider

Searches for users that have a specific attribute with a specific value.

Specified by:

searchForUserByUserAttributeStream in interface UserQueryMethodsProvider

Parameters:

realm - a reference to the realm.

attrName - the attribute name.

attrValue - the attribute value.

Returns:

a non-null Stream of users that match the search criteria.

synchronizeRegistrations

public boolean synchronizeRegistrations()

addUser

public UserModel addUser(RealmModel realm,
 String username)

Description copied from interface: UserRegistrationProvider

All storage providers that implement this interface will be looped through. If this method returns null, then the next storage provider's addUser() method will be called. If no storage providers handle the add, then the user will be created in local storage. Returning null is useful when you want optional support for adding users. For example, our LDAP provider can enable and disable the ability to add users.

Specified by:

addUser in interface UserRegistrationProvider

Parameters:

realm - a reference to the realm

username - a username the created user will be assigned

Returns:

a model of created user

removeUser

public boolean removeUser(RealmModel realm,
 UserModel user)

Description copied from interface: UserRegistrationProvider

Called if user originated from this provider. If a local user is linked to this provider, this method will be called before local storage's removeUser() method is invoked. If you are using an import strategy, and this is a local user linked to this provider, this method will be called before local storage's removeUser() method is invoked. Also, you DO NOT need to remove the imported user. The runtime will handle this for you.

Specified by:

removeUser in interface UserRegistrationProvider

Parameters:

realm - a reference to the realm

user - a reference to the user that is removed

Returns:

true if the user was removed, false otherwise

getUserById

 String id)

Description copied from interface: UserLookupProvider

Returns a user with the given id belonging to the realm

Specified by:

getUserById in interface UserLookupProvider
