In an environment where there is no plan to share data between NIS and LDAP naming services clients
In such an environment, an N2L server would serve as an excessively complex NIS master server.
In an environment where NIS maps are managed by tools that modify the NIS source files (other than yppasswd)
Regeneration of NIS sources from DIT maps is an imprecise task that requires manual checking of the resulting maps. Once the N2L service is used, regeneration of NIS sources is provided only for backout or reverting to NIS.
In an environment with no NIS clients
In such an environment, use Solaris LDAP naming services clients and their corresponding tools.
