   Protocol (LDAPv3) as defined in RFC 3377.  It also supports a variant
   of version 2 of LDAP as defined by U-Mich LDAP and, to some degree,
   RFC 1777.  Version 2 (all variants) should be viewed as obsolete.
   Version 3 should be used instead.
   .LP
   For backwards compatibility reasons, the library defaults to version 2.
   Hence, all new applications (and all actively maintained applications)
   should use
   .BR ldap_set_option (3)
   to select version 3.  The library manual pages assume version 3
   has been selected.

 .SH CONTROLS  
 This library supports both LDAP Version 2 and Version 3, with the Version 2  
 protocol selected by default.  
 LDAP Version 3 operations can be extended through the use of controls. Controls  
 can be sent to a server or returned to the client with any LDAP message.  
 Extended versions of the standard routines are available for use with  
 controls. These routines are generally named by adding  
 .BR _ext  
 to the regular routine's name.  
 .SH UNIFORM RESOURCE LOCATORS (URLS)  
 The  
 .BR ldap_url (3)  
 routines can be used to test a URL to see if it is an LDAP URL, to parse LDAP  
 URLs into their component pieces, and to initiate searches directly using  
 an LDAP URL.
