[SunHELP] Maximum users on a Solaris 2.6 server

[Steven B. Parsons]

Nicholas -

Thanks for the prompt response .

The problem is when I type useradd , put in a username
its not added to /etc/passwd or the shadow file , no error
is given just the user is never added.

As you see below the box is very close to 4k users.

Why I cant add anymore users is what im trying to find out.

Steve
