Update.
1999-06-11 Thorsten Kukuk <kukuk@suse.de> * nscd/nscd.c: Add -S options for separate caching of data for every user. So one user couldn't see the data another user has gotten with his credentials. * nscd/nscd.h: Add new prototypes. * nscd/cache.c: Compare owner of cache entry if in secure mode. * nscd/connections.c: Check on shutdown if caller really was root. In secure mode get uid of caller. * nscd/grpcache.c: Add support for new secure group mode. * nscd/hstcache.c: Add support for new secure hosts mode. * nscd/pwdcache.c: Add support for new secure passwd mode.
