Bind user error normally points to one of two things - 1.  Bind user is not entered correctly or does not have appropriate permissions 2. Context is entered wrongly.

There is a utility called ldap.exe that you can google.  You run it from a windows pc but it will give you more detailed info on where your problem is.

Install webmin.  It's an open sourced cPanel for Linux servers.   Runs it's own web service off a higher port of your choosing.  Can limit access to webmin to cartain IP addresses or IP address ranges.   And it has tools to help admin the server ... one is a module for LDAP ... that allows you to (once configured with proper bind credentials) browse the entire LDAP 'tree'.

Other than that, one could install openldap which contains command line tools ... ldapsearch ... which are less user friendly than webmin.

Download tar.gz to your server.

I was excited to see in 3.3 there is actually a Moodle LDAP connection test.  My LDAP server works so not sure what error messages it might throw but it does at least tell you if it connecting properly!  The ldap.exe is a pain to have to run from a windows device but it does give you good information.  Just run it off some pc in your network.
