      Solaris OS has a core conception --- user and user account management .User has all of processes and files . If OS has no users,it can not finish data operation and system management. User must has an account to login the system,and he can finish the  prospective work. As Solaris system administrator, it is a key job to manage user and account(there are some conception about user group,but I do not introduce this).

     The loginning name has 8 characters at most. After creating the account, we can :1.start Shell; 2.implement application program ;3.call all kinds of system serveice. User management refer to 3 document: 1./etc/passwd: user acconut information. 2./etc/group:group configuration information; 3./ect/shadow: account password and all kinds of control information. Solaris integrate user account management into SMC,and SMC help administrators manage system and applications.Besides SMC, we can finish management work by command-line.

     1.add user:#useradd -u uid -g gid -d home_directory -s path_to_shell -c comment login_name 

    2 change user account attribute:usermod

    3 delete user:userdel

DEMO 1

add user sun1 and sun2:

#useradd -u 200 -g other -d /export/home/sun1 -m -c "first user" -k /etc/skel sun1

#useradd -u 300 -g other -d /export/home/sun2 -m -s /usr/bin/sh -c "second" sun2

change user UID,and change the password:

#usermod -u 400 sun1

#grep sun1 /etc/passwd

#passwd sun1

change user and user home:

#usermod -d /export/home/sun22 -m -l sun22 sun2

#ls -ld /export/home/sun22

user accuont control strategy,lock and unlock:

#usermod -f 10 -e 12/31/2008 sun1

#passwd -l sun1

#passwd -u sun1

delete user

#userdel -r sun1
