It depends on your use case. If you are managing 100s of machines, you
want a centralized authentication/authorization system. Otherwise trying
to manage 100s of passwords or authentication tokens is a nightmare.
As for centralized administration on Unix like systems, I have used
OpenLDAP as a backend to NIS. There is a NIS schema for LDAP which
makes the configuration pretty straightforward using the nss_ldap and
the pam_ldap plugins. There is also an LDAP schema for sudo which
means you can centralize sudo access as well.
