LDAP_URL(3) Library Functions Manual LDAP_URL(3)
ldap_is_ldap_url, ldap_url_parse, ldap_free_urldesc - LDAP
Uniform Resource Locator routines
OpenLDAP LDAP (libldap, -lldap)
#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;
void ldap_free_urldesc( LDAPURLDesc *ludp );
These routines support the use of LDAP URLs (Uniform Resource
Locators) as detailed in RFC 4516. 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 LDAP 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().
