Contacts LDAP Account on 10.11 (El Capitan) I am trying to set up an LDAP account for the Contacts application in the 10.11 (El Capitan) OS X version. I need it, for example, to be able to autocomplete addresses via the Mail application.

I've been using this feature in older versions without problems, but with 10.11 I am unable to retrieve contacts from the server. Even on 10.11.3 - connecting to an OpenLDAP 2.4 server or to Active Directory 2008 R2 using a "formal" dn, login &amp; password fails.

In this version the setup can be done vie the Internet Accounts at the System Preferences pane or directly in the Contacts app. The first nuisance is that the password can only be entered once the account has been enabled on the preferences on the Contacts app. Having found this, the new account only appears after restarting the app, and then, searching anything always returns an empty set.

The information to connect to the server (host, user dn, password, base...) is valid and works in previous releases. Doing an ldapsearch works fine as it does configuring the LDAP contacts in Thunderbird in OS X. It seems to me that it is related to the OS.

Is this a bug or is there a procedure to connect to LDAP?
I had checked network packets with wireshark and found that OSX 10.11 and 10.11.1 do not send bindRequest to LDAP server (only searchRequest and unbindRequest), nevertheless authenticate method was configured as 'simple authentication'.
This is bug.
