Class LdapPasswordProvider

java.lang.Object

ome.security.auth.ConfigurablePasswordProvider

ome.security.auth.LdapPasswordProvider

All Implemented Interfaces:

PasswordProvider, PasswordUtility, ApplicationContextAware

public class LdapPasswordProvider
extends ConfigurablePasswordProvider

LDAP PasswordProvider which can create users on request to synchronize with an LDAP directory. Assuming that a user exists in the configured LDAP store but not in the database, then a new user will be created. Authentication, however, always takes place against LDAP, and changing passwords is not allowed. Note: deleted LDAP users will not be removed from OMERO, but will not be able to login.

4.0

Method Detail

hasPassword

public boolean hasPassword(String user)

Only returns if the user is already in the database and has a DN value in the password table. Note: after a call to checkPassword(String, String, boolean) with this same user value, this method might begin to return true due to a call to LdapImpl.createUser(String, String).
