Here's how I comfigured mine.Default domain: is your FQDN for your domain. In my configuration its corp.SHORTDOMAINNAME.local.DNS Servers: your dns server. I use the IP Address for ours.LDAP Servers: I put two entries in here, but you really only need one. I personally entered the ip address of my AD server, and the FQDN of my AD server. (The FQDN of your AD server should be SERVERNAME.corp.SHORTDOMAINNAME.local.Use TLS: I did not check this. You may have to depending on what version of AD your running.Connection InformationSearch User: a username that has look up rights in AD. I had to user SHORTDOMAINNAME\username here to get it to bind right.Password: the accounts password.Search Base: I don't think that this is neessary, but I was playing with it a little.

What we have installed on our Windows 2008 server though doesn't seem like its particularly important however.Q: if it isn't needed, why the error?A: The search user account is only needed for the lookup portion of the plugin. Authentication should work with out it.Q: Anyway, I don't see any type-ahead or lookup
happening when I create a new ticket and I *thought* I had this working
in the old 1.6 installation I used to have (but I didn't upgrade it, I
started from scratch).A: There was no LDAP plugin for 1.6. Plugins were just introduced in version 1.8.1. There was a mod on the forum that you might have used, but it was written by a community member and not the osTicket devs.Q: Are there any simple step by step instructions to
configure this plugin or at least a screen shot of a typical
installation you can share? A: No, but I have just replied with some generic instructions that might get you going. Unfortunately there are a lot of ways that your AD could be configured, and your organizational units can vary from everyone else's.
