Authenticated users are not allowed to access admin pages (etherpad 1.8.7 and above)

[AyoubHabra]

After upgrading etherpad instance from version 1.8.4 to 1.8.7. Ldap users were not allowed to access admin pages despite being successfully authenticated by ep_ldapauth. And, by reverting to the 1.8.4 (or 1.8.5) version with the same settings, it works again. I think it's related to security fixes applied to Etherpad. Can you help me with this issue please?

Please note: This repository is up for adoption. I no longer have the time to maintain it, nor does my work require it anymore so I have no need to work on it.

As an FYI PR #47 may be a fix for you. But again, I don't have the time (nor inclination to do the validation or testing)
