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;

       void ldap_free_urldesc( LDAPURLDesc *ludp );


DESCRIPTION

       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  compo-
       nent  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().
