Ldap issue

HI,

We want to go ahad with new LDAP Signing and Channel Binding Changes in Active Directory

we have installed the March updates on both our server 2012 R2 DC and server 2016 member servers and set the

DC policy

Domain controller: LDAP server channel binding token requirements = Always

Domain controller: LDAP server signing requirements = Require singing

On member servers:

Network security: LDAP client signing requirements  = Require singing

Also set the registry on DC to highest:

Enable LDAP Signing and LDAP Channel Binding

LDAPServerIntegrity = 2

LdapEnforceChannelBinding = 2

But now the directory logs showa these warning for all of the memeber server: 

Internal event: An LDAP client connection was closed because of an error. 

Client IP:
10.0.10.11:50039 

Additional Data 
Error value:

Internal ID:
