* For sites with broken group and/or passwd database, the auto-propagate
option of nscd can prevent creating ID lookup entries from the results
of a name lookup and vice versa. This usually is no problem but some
site might have problems with default behavior.
Implemented by Ulrich Drepper.
* Iterating over entire database in NIS and NIS+ can be slow. With the
SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
to trade time for memory. The entire database will be read at once.
Implemented by Ulrich Drepper.
