I answered a message on the OS X Server Administrator's list regarding how to set up a SonicWall Pro Series appliance to authenticate users against OpenDirectory. I promptly started receiving more questions directly from people trying to accomplish the same thing. Since not all lists are attachment-friendly, here are snapshots of the settings I'm using in one case. Please note that a) this could be more secure, and b) I've redacted where necessary.
Step 1: Log into the firewall and choose the "Users" tab in the nav bar. You should see a dropdown menu with authentication options.

Step 2: Choose "LDAP + Local Users" and then click the "Configure..." button.
Step 3: Match up your settings as necessary:

Move onto the "Schema" tab:

Then, move onto the actual LDAP configuration. Clearly, this needs to match up to your configuration on the OS X Server side, which can be checked in Server Admin.app utility:

The remaining tabs are really situation dependent, so, I won't cover them here. The above information should be enough for a successful "test" on the "Test" tab. In figure 4, by the way, I'm not using groups, so, there's a bit of a bogus value in there.
Questions? Post 'em and I'll see what I can do.

Yeah....got it, thanks.
Yeah....got it, thanks. That was a result of porting the site over from WordPress....and trying not to visit every post in the process!
It looks like the problems
It looks like the problems that we initially had with getting this to work may have been down to our firmware on the Sonicwall being out of date. We recently flashed up to SonicOS Enhanced 4.0.0.2-51e and LDAP connection now works just fine. Hope this helps anybody who was having problems.
