The user and group ID will be set according to their values in the _/etc/passwd_ file. There is one exception if the user ID is zero. In this case, only the primary group ID of the account is set. This should allow the system administrator to login even in case of network problems. The environment variable values for *$HOME*, *$USER*, *$SHELL*, *$PATH*, *$LOGNAME*, and *$MAIL* are set according to the appropriate fields in the password entry. *$PATH* defaults to _/usr/local/bin:/bin:/usr/bin_ for normal users, and to _/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin_ for root, if not otherwise configured.
