While I admit, it sounds weird to bridge LDAP and Coppermine, since it isn't exactly a BBS, I figured it was the easiest and most portable way to allow authentication between Coppermine and a backend LDAP Directory. For the moment, it's a work in progress, but after seeing some requests, I figured I'd drop the line that I had something working and (for the most part) it works. The sad part is that while it is designed as a bridge, it doesn't exactally store things like Group information in the LDAP directory but Coppermine doesn't use it's internal groups if bridging is enabled. It's caused some interesting issues. If someone knows more about Coppermine's interaction and requirements for bridging, I do accept help to figure it out.
At any rate, here is the bridge file as I have it so far.
