DESCRIPTION

These routines support the use of LDAP URLs (Uniform Resource Locators). LDAP URLs look like this:

ldap://hostport/dn[?attributes[?scope[?filter]]]

where:
hostport is a host name with an optional ":portnumber"
dnis the base DN to be used for an LDAP search operation
attributes is a comma separated list of attributes to be retrieved
scope is one of these three strings: base one sub (default=base)
filteris LDAP search filter as used in a call to ldap_search(3)

e.g., ldap://ldap.itd.umich.edu/c=US?o,description?one?o=umich

URLs that are wrapped in angle-brackets and/or preceded by "URL:" are also tolerated.

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, one of these values is returned:

LDAP_URL_ERR_NOTLDAP

				- URL doesn’t begin with "ldap://" LDAP_URL_ERR_NODN
				- URL has no DN (required) LDAP_URL_ERR_BADSCOPE	- URL scope string is invalid LDAP_URL_ERR_MEM
				- can’t allocate memory space

ldap_free_urldesc() should be called to free an LDAP URL description that was obtained from a call to ldap_url_parse().

ldap_url_search() initiates an asynchronous LDAP search based on the contents of the url string. This routine acts just like ldap_search(3) except that many search parameters are pulled out of the URL.

ldap_url_search_s() performs a synchronous LDAP search based on the contents of the url string. This routine acts just like ldap_search_s(3) except that many search parameters are pulled out of the URL.

ldap_url_search_st() performs a synchronous LDAP URL search with a specified timeout. This routine acts just like ldap_search_st(3) except that many search parameters are pulled out of the URL.
