I have 20 Solaris 8 machines and I would like to have these machines do user authentication through one machine acting as server instead of having to maintain a user list on every machine. What can I do to achieve this?
Your issue can be resolved by using either NIS or LDAP but
according to me it would be good if you start with NIS once you feel comfortable with NIS then go for LDAP.
May be following link helps you doing this:-
