Re: Is ldap_bind() mandatory before each ldap_search() call?
Someone who knows Active Directory might give better answers, since
your remaining questions relate to the server, not the client. Try
your sysadmin, email@example.com, or some AD-specific group.

Ah, OK. In that case you just have to do what the server says.
The LDAP spec doesn't require it but the server may, as you see.

As far as the LDAP spec is concerned there aren't any. Check with your
server's sysadmin, these may be per-server settings (if they are set).

The latter. Well, the client cal poll for results asynchronously even
if it isn't expecting any, and check for LDAP_SERVER_DOWN.
