Problem egroupware 16.1 and contact from ldap

[rpiet]

Hi,
I installed Egroupware 16.1.005 on Ubuntu 16.04 with LDAP authentication on another ubuntu server 16.04.
Authentication works.
I also want to use contacts in LDAP but when I created a contact I have the following error.

An error happened (Error): Call to undefined method EGroupware\Api\Contacts\Ldap::ldapConnect()

Thank you for your help

I solved the problem by creating the tree in LDAP.
I configured the acl as described in egroupware / doc / ldap / README.contacts.
Creating, editing, and deleting works, but I can not move a contact from one address book to another
