Hello,

Hello,

I'm playing around with 2008 server in a non production environment. I am
getting this event but the link doesn't seem to work.

Log Name: Directory Service
Source: Microsoft-Windows-ActiveDirectory_DomainService
Date: 6/12/2008 4:04:10 PM
Event ID: 2886
Task Category: LDAP Interface
Level: Warning
Keywords: Classic
User: ANONYMOUS LOGON
Computer: CSD-6700.csd.lan
Description:
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 (integrity 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 summary event once every
24 hours indicating how many such binds occurred. 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.

For more details and information on how to make this configuration change to
the server, please see http://go.microsoft.com/fwlink/?LinkID=87923.

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.

Thanks - good to know I'm not alone. Seems like just about every link in
the even that is set off in 2008 goes nowhere.
