ldap_search_ext_s fails with "Operations error" when using root as base dn - openldap-technical

15 Dec 2021


      Hi,
When I try to query the root of my AD with
scope LDAP_SCOPE_SUBTREE ldap_search_ext_s() fails with "Operations error".
It happens only when I set the ldap_search_options.base to the domain DN
(eg. DC=example,DC=com). If I use a more specific base, such as
CN=Computers,DC=example,DC=com the operation succeeds. Is there a
limitation to the search function?
pseudocode snippet:
```
ldap_search_options ldap_opts;
ldap_opts.base    = "DC=example,DC=com";
ldap_opts.scope   = LDAP_SCOPE_SUBTREE;
```
