ldap - Why does (package) nslcd recommend nscd? - Ask Ubuntu

nscd (Name Service Cache Daemon) is a GNU C Library -- A daemon which handles passwd, group and host lookups for running programs and caches the results for the next query. You should install this package only if you use slow Services like LDAP, NIS or NIS+ However, if nscd is in a hung state, it may not be able to even give that simple won't do answer, so that won't necessarily help. But that's probably the closer to what you want you will get short of disabling nscd altogether. nscd is a caching daemon, it's meant to improve performance. Disabling it would potentially make those look ups slower. Nscd itself is a caching daemon for NSS functions. So the focus is a bit different than native caching nameservers.
