Unable to add LDAP server in Mac OS 10.11
I must be missing something simple since this is a feature that has been available in Mac OS for years and years but I am unable to add an LDAP account in Mac OS 10.11 El Capitan.
Actually I can add a new account (which uses Internet accounts) but when I choose Simple Authentication I am not presented with a place to enter the user name and password, I did find a bit later that I can add the account without the credentials, then go into the Contacts application's preference panel and add the user name and password there but even after doing that I am unable to search the LDAP server.
I have also verified that if I use the migration tool to move an account from a machine running an older system to 10.11 the LDAP account is marked as inactive and adding the username and password in that case also does not work for me.
Can anyone tell me how to add authenticated LDAP accounts to 10.11 El Capitan? This feature is very important to us because we use it to allow our Mac users to access our shared address book.
Thanks in advance.
