Solaris is a Unix operating system often used for servers developed by Oracle. Solaris is a multi-user operating system. Like other UNIX operating systems, every user account on Solaris has its own home folder and permissions settings. Solaris includes the standard UNIX “usermod” command which changes a user account’s name and automatically takes care of renaming the home folder and adjusting system permissions. You must have root, or administrator, permissions on the system to change a user account’s name.
