To do that, you need to enable authentication through LDAP in the MDM configuration file, which is a template that contains the configuration information related to LDAP.
Note that the configuration file varies with the MDM version you are using. Before MDM Release 6.0, it was login-config.xml_LDAP; since MDM Release 6.0, it is jass.conf.
In the configuration file, the option LdapDirect specifies the LDAP authentication method to use. If it is set to false, the indirect authentication method is used, in which an admin user must browse through the LDAP directory to find the distinguished name (DN) for the given username.
In this case, the LdapAdminDN, LdapAdminPassword, searchBase and searchFilter parameters must be set.
This article assumes that you have a good knowledge of LDAP and are familiar with LDAP configuration.
This article applies to Talend MDM v5.0.x or higher.
