LDAP Proxy Server Not Finding Users

New Contributor

I have setup an AWS instance holding the NetBoot/SUS/LDAP Proxy appliance inside of a VPC that has a VPN tunnel to our network (long story short: we have an ldap proxy server running and have tested connections back and forth).

We've tested to and from connections, from our network to the ldap proxy instance and vice versa. I just can't seem to get authentication working. When I try to use the "Test" functionality in our LDAP config in the JSS, we get the following error:

Error: javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid Credentials]
Suggestion: Ensure that the username and password provided are valid.

I'm pulling the distinguished username straight from our AD, so I know that's correct. We've also tried different users, so something is up with the proxy I think. Anyone dealt with the same thing that could shed some light on the situation? Thanks!
