The userdb module uses berkley db or gdbm databases for authentication.
These are good for smaller setups, less than a few hundred users.
However, as these databases get large they will decrease in performance.
Solutions like mysql and openldap are designed to handle very large
databases, and they don't degrade nearly as badly as your database
grows. There is also the fact that it is more efficient to maintain a
large list of users with something like SQL or LDAP. For one it's easy
to automate. For two you don't have to rebuild the entire database when
ever you make a change.

Those of you who think they know everything are very annoying to those
