Hi, Joseph. >Was this removed in the newest version? Yes, it was removed, as it wasn't considered a safe practice. Please consider creating a user with sufficient rights at your LDAP server.

That is unfortunate. Anonymous binding is a requirement for this project.

You could write a custom authentication script. Check out the basic script that ships with the Gluu Server or [one of the basic scripts in Github](https://github.com/GluuFederation/oxAuth/tree/master/Server/integrations)

I am finding the opposite reaction on the server, when the external ldap server enabled with anonymous access; the refresh works. When I disable the anonymous access on the ldap server... the cache refresh fail with the following error: **I am using community version of gluu server [4.1] [gluu.oxtrust.ldap.cache.service.CacheRefreshTimer] (CacheRefreshTimer.java:204) - Exception happened while executing cache refresh synchronization org.gluu.persist.exception.operation.ConfigurationException: Failed to create LDAP bind connection pool!
