Contacts LDAP Account on 10.11 (El Capitan)

Solution 1:

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.

Solution 2:

same here. and I checked the ldap server, the log shows it never be connected. it may be the 10.11 problem
