Windows NT network client computer users gain access to network resources with a single logon and password, from any computer in their own "domain" or other "trusted" domain. No matter which computer they use, their own user environment will be established for them by the Windows NT server at logon. This environment and various other user attributes are maintained by way of the User Manager for Domains tool.
Similar (though not equivalent) information in the world of the Solaris system administrator is stored in the /etc/passwd, /etc/groups, .profile, and .cshrc files.
You use User Manager for Domains for many common tasks, including:
Managing passwords, including resetting forgotten passwords
Setting up logon hours
Setting account expiration dates
Managing user accounts, including creating, deleting, altering, naming, and disabling
Creating and modifying a path to the user's profile
Creating logon scripts for users and specifying their home directories
Managing groups, including creating, deleting, and changing them and their membership
Managing security policy, including number of failed logons permitted, users' and groups' rights, and audit policy
Managing trust relationships among Windows NT domains
