Describe the bug

When I try to configure the OpenLDAP authentication provider, I get an error: Result Code 32 "No Such Object".

To Reproduce

1. Go to Rancher's OpenLDAP authentication provider configuration page.

2. Fill these following fields:

   • Hostname
   • Port
   • TLS (check)
   • Certificate
   • Service Account Distinguished Name
   • Service Account Password
   • User Search Base

3. Use a valid LDAP user for the test.

4. Submit form by clicking on "Enable" button.

Result

Check Rancher logs using the following command:

kubectl -n cattle-system logs -l app=rancher -c rancher --follow

You should see something like this:

2021/10/25 09:51:20 [ERROR] API error response 401 for POST /v3/openLdapConfigs/openldap?action=testAndApply. Cause: LDAP Result Code 32 "No Such Object":

Expected Result

The OpenLDAP authentication should be enabled.

Additional context

By investigating the code and from my understanding, I think the problem comes from the request that is made on lines 71 to 78 in ldap_client.go. Unfortunately, I don't know how to solve the problem. Do you have an idea?
