Note

If the Auto import users option is checked, the LDAP settings of any new user who logs into the Centreon interface will automatically be imported into Centreon (name, first name, e-mail address, etc.). ACL profiles will be applied on access (link to ACL). However, if this option is not checked, only the users imported manually will be able to authenticate.
