Odd.
When you installed XOOPS, you created a superuser account for the webmaster. This account is always available through the default XOOPS authentication method. So if you selected that as your login option, then you should always be able to login.
So I do not understand why you can't login when you have the default method selected, and not LDAP. For LDAP you need to configure both the XOOPS site and the LDAP server correctly, and then you would at least know you were dealing with LDAP (ie know the name).
So what really is the problem here? You should be able to login using the default login method (XOOPS authentication). If you've logged in using that, you can configure your XOOPS site to authenticate via the LDAP server.
