- Restart system.

### Test LDAPS
After restart system, we can connect to the LDAP server over SSL.
Now let us try to connect to LDAP Server (with and without SSL) using the ldp.exe tool.

Connection strings for:

- `LDAP:\\ad.iredmail.org:389`
- `LDAPS:\\ad.iredmail.org:636`

- Click `Start` on bottom-left corner of your Windows OS,
- Click `Search` on top-right corner, enter `ldp.exe` in the input box.
- Connection and fill in the following parameters and click OK to connect:

- If Connection is successful, you will see the following message in the ldp.exe tool:

- To Connect to LDAPS (LDAP over SSL), use port 636 and mark SSL. Click OK to connect.
