Where is opendirectory/accounts/login information stored on macos

Question

I have encountered this problem of slow login (How can I debug an extremely slow login?), and have not found a solution. However, this phenomenon does not exist if I boot up into a fresh system. Since I have a backup of the system sometime ago that was working, I think that if I copy all the system files from that backup over, and then reinstall the system, the issue should be resolved. However, I don't want to copy all system files, because some of them can be outdated, some of them can be databases that are regularly updated, etc. Hence, I wonder if I can just copy over the opendirectory folders over and see if things get better (I have backups so I'm not afraid of breaking the system), but I don't know where is that information stored on disk. Where is the data files stored for opendirectory?

Answer 1

It is stored in /private/var/db/dslocal/nodes.
