Editing the /etc/passwd file

Editing the /etc/passwd file

Although using the Account Manager is preferred for adding and maintaining users and groups, administrators accustomed to editing /etc/passwd directly can simply do so -- unless your system is configured with the Improved or High security profiles. If this is so, you must also run the authck(ADM) command with the -p and -s options to update the accounts database. With the lower security profiles, you can edit /etc/passwd without running authck.
