dslocal files

[Cice]

im not sure, if i understand the whole concept behind directory services and dslocal, but last week i had a very annoying problem with my leopard installation: every time i tried to add directories to file sharing (either in the pref pane or via "get info" in finder) coreservicesd crashed and i had to force a reboot. i deleted every preference file for which it's relevant for file sharing or networking in general, but i couldn't get this fixed. so i thought, time to give snow leopard a shot, installed it and transferred my files from my timemachine backup, but then the problem persisted, so this time i went deeper and found that /var/db/dslocal/..../SharePoints.plist was corrupt, i restored this file from an older timemachine backup and i finally could use filesharing again! great success. but then i started thinking... whatever smashed this sharepoints.plist could have smashed other files in dslocal, because, i think the underlying problem was a corrupt file system on my old leopard installation. so, is there any possibility to check dslocal for consistency? is it safe to delete the whole directory and let it get rebuilt by mac os x, OR, replace it with an older version from my backup disk?
