* nscd/nscd.h (struct database_dyn): Add propagate field.
* nscd/nscd_conf.c (nscd_parse_file): Parse auto-propagate lines. * nscd/nscd.conf: Add auto-propagate lines. * nscd/connections.c (dbs): Initialize .propagate fields. * nscd/grpcache.c (cache_addgr): Do not add ID entry for name lookups and vice versa if propagation is disabled for the database. * nscd/pwdcache.c (cache_addpw): Likewise.
