authentication ldap error

[mablasfor]

Hi!
I have a problem with the login
I changed the authentication-database for authentication-ldap and modified ldapauth.properties.
When I log with the account created in openldap example@example.com I get the following error:
Error: The connection is not possible at the moment. Please try again later. (LGI-0005, -142,677,246-11)

open-xchange.log.0 shows this:
