NAME
ldap_is_ldap_url, ldap_url_parse, ldap_free_urldesc - LDAP
Uniform Resource Locator routines
LIBRARY
OpenLDAP LDAP (libldap, -lldap)
SYNOPSIS
#include <ldap.h>
int ldap_is_ldap_url( const char *url )
int ldap_url_parse( const char *url, LDAPURLDesc **ludpp )
typedef struct ldap_url_desc {
char * lud_scheme; /* URI scheme */
char * lud_host; /* LDAP host to contact */
int lud_port; /* port on host */
char * lud_dn; /* base for search */
char ** lud_attrs; /* list of attributes */
int lud_scope; /* a LDAP_SCOPE_... value */
char * lud_filter; /* LDAP search filter */
char ** lud_exts; /* LDAP extensions */
int lud_crit_exts; /* true if any extension is critical */
/* may contain additional fields for internal use */
} LDAPURLDesc;
ldap_free_urldesc( LDAPURLDesc *ludp )
DESCRIPTION
These routines support the use of LDAP URLs (Uniform
Resource Locators) as detailed in RFC 2255. LDAP URLs look
like this:
ldap://hostport/dn[?attrs[?scope[?filter[?exts]]]]
where:
hostport is a host name with an optional ":portnumber"
dn is the search base
attrs is a comma separated list of attributes to request
scope is one of these three strings:
base one sub (default=base)
filter is filter
exts are recognized set of LDAP and/or API extensions.
Example:
ldap://ldap.example.net/dc=example,dc=net?cn,sn?sub?(cn=*)
URLs that are wrapped in angle-brackets and/or preceded by
"URL:" are also tolerated. Alternative schemes such as
ldaps:// and ldapi:// may be parsed using the below routines

as well.
ldap_is_ldap_url() returns a non-zero value if url looks
like an LDAP URL (as opposed to some other kind of URL). It
can be used as a quick check for an LDAP URL; the
ldap_url_parse() routine should be used if a more thorough
check is needed.
ldap_url_parse() breaks down an LDAP URL passed in url into
its component pieces. If successful, zero is returned, an
LDAP URL description is allocated, filled in, and ludpp is
set to point to it. If an error occurs, a non-zero URL
error code is returned.
ldap_free_urldesc() should be called to free an LDAP URL
description that was obtained from a call to
ldap_url_parse().
