In my Windows Server 2008 R2 OS in the Event Viewer there is an error pertains as ADAM(instance1) LDAP Event ID 2886states-(The security of this directory server can be significantly enhanced by configuring the server to reject SASL (Negotiate,Kerberos,NTLM or Digest) Ldap binds that do not request signing (intergrity verification) and LDAP simple binds that are performed on a cleartext (non-SSL/TLS-encrypted) connection. Even if no clients are using such binds,configuring the server to reject them will improve the security of this server. Some clients may currently be relying on unsigned SASL binds or LDAP simple binds over a non-SSL/TLS connection,and will stop working if this configuration change is made.To assist in identifying these clients,if such binds occur this directory server will log a summery event once every 24 hours indicating how many such binds occured.You are encouraged to configure those clients to not use such binds.Once no such events are observed for an extended period,it is recommended that you configure the server to reject such binds. You can enable additional logging to log an event each time a client makes such a bind,including information on which client made the bind.To do so Please raise the setting for the "LDAP Interface Events" event logging category to level 2 or higher). What is this error? And What is the remedy for this error? MumthazMuhsin

This type of event is common in cases, when there is simple insecure binding.
