<p>The <strong>ldap_compare_s()</strong> function is used to perform an LDAP
|
|
compare operation. The API uses as input the distinguished name (DN) of the
|
|
entry on which to perform the compare, and uses an <em>attr</em> and <em>
|
|
value</em> (the attribute type and value to compare to those found in the
|
|
entry).</p>
|
|
|
|
<p>Binary values are not supported by this API. Use <a href=
|
|
"ldap_cmp_ext_s.htm">ldap_compare_ext_s()</a> if binary values must be
|
|
compared. <strong>ldap_compare_s()</strong> is a synchronous request.</p>
|
|
|
|
<br>
|
|
|
|

|
<h3>Authorities and Locks</h3>
|
|
|
|
<p>No i5/OS authority is required. All authority checking is done by the LDAP
|
|
server.</p>
