PHP ldap_read（）没有这样的对象

Question

I can successfully bind to ldap using ldap_bind() .

But when I come to do an ldap_read() using the Distinguished Name (DN) that I bound with, I get the error

No such object

For example

if (ldap_bind($ldap, $dn, $password))
{
  ldap_read($ldap, $dn, '(objectclass=*)');
}
else
{
  echo "Bind failed";
}

No matter what I try as a filter, I always get this error.

Answer 1

I have solved the problem. It turned out to be a permissions problem in the directory. The user didn't have read permission, even for their own entry.
