ldap_connect
  Connect to an LDAP server
  
 
 
  Description
  
   resource ldap_connect
    ([ string $hostname = NULL
   [, int $port = 389
  ]] )
  
  
 
  Parameters
  
   
    - 
     
hostname
      - 
      
       If you are using OpenLDAP 2.x.x you can specify a URL instead of the
       hostname. To use LDAP with SSL, compile OpenLDAP 2.x.x with SSL
       support, configure PHP with SSL, and set this parameter as  
       ldaps://hostname/.
      
      
    
    - 
     
port
      - 
      
       The port to connect to. Not used when using URLs.
      
      
    
   
  
  
 
  Return Values
  
   Returns a positive LDAP link identifier on success, or FALSE on error.
   When OpenLDAP 2.x.x is used, ldap_connect will always
   return a resource as it does not actually connect but just
   initializes the connecting parameters.  The actual connect happens with
   the next calls to ldap_* funcs, usually with
   ldap_bind.
  
  
   If no arguments are specified then the link identifier of the already
   opened link will be returned.
