[aur-general] Slight Modification to core package?

Hello everyone, I wasn't sure where to ask this, but here goes: Apparently the core sudo package is not compiled with the sssd flags. Since i need to recompile the package with sssd support, would I just upload the "sudo-sssd" package (or whatever i end up calling it), to the aur, or is there some more official way of going about this? NM
