only limited users should login in NIS (not all nis users) RHEL 5.4
i have a NIS master server and 4 NIS clients. out of 4 nis clients two are acting as login servers ie users will login and do all their stuffs and the remaining two are application servers. But sometimes users login into applications servers and started doing all their developer's job. i want to allow only a limited number of users to login into this application users not all the users who are all part of the nis domain.
all the systems are running RHEL 5.4 on hp's proliant x86_64 based servers. Please advice me how should i proceed? enabling ip tables is not possible in my environment.
