- Database dumps and loads (via krb_util, which is used by kprop) are
- slow when the database is that big (apparently order n log n). But
- ticket requests (kinit) and database updates (kadmin and kpasswd) are
- still very fast (apparently order log n). Also, the ndbm files get
- really big (I think I tested it on a Sun with 10,000 principals, and
- the file was 5 meg in size), if this is a problem on your system.
-
- A kprop/kpropd that sends only updates is critical for realms that
- have # of principals in the tens of K. In this case, kdb_util should
- only be used in emergencies.
