Hi all. be gentle, its my first time 
I seem to have had this isse dumped on me and could do with help/advice.
We have several Solaris10 servers, authentication is done per server using the usual useradd and the passwd/group/shadow files.
we're now at a point where we need some way of managing/authenticating these account centrally.
Has anyone got any advice on where i can go with this? we wont be hitting any AD kit, so ill need to set up from scratch.
Thanks in advance
I would first look at LDAP.
There's also Sun DIrectory Services Sun Java System Directory Server Enterprise Edition
LDAP will be a good option as well
Thanks for the replies guys....i suppose this may be a little easier if i knew anything about LDAP 
I suppose i best read up.
Can LDAP give me the central repository that im looking for, i though it was mainly used as a transport????
Excuse my ignorance.
Cheers
LDAP directories are capable of becoming the central repository for all user, group, and access control information
