NetAuth Localizer
The localizer is a component of the NetAuth stack which directly
manages passwd, group, and shadow databases. The service edits
these files periodically to add and remove users and groups that are
above the threshold of an optional cutoff specified by an
administrator, by default UIDs and GIDs greater than 2000.
Why not NSS?
NSS is shockingly difficult to work with, and surprisingly buggy internally. Its also not available in a meaningful way outside of glibc, which limits its usefulness. Furthuremore, NSS uses shared modules which have to be loaded into a program's address space, or otherwise loaded by some persistent process on the system. This makes it cumbersome ti isolate security domains with potentially every application on the system needing to load NSS modules.
