NAME
       sulogin - access single-user mode

SYNOPSIS
       sulogin

DESCRIPTION
       The sulogin utility is automatically invoked by init when the system is first started. It prompts the user to type a user name and password
       to enter system maintenance mode (single-user mode) or to type EOF (typically CTRL-D) for normal startup (multi-user mode). The user should
       never directly invoke sulogin. The user must have the solaris.system.maintenance authorization.

       The  sulogin utility can prompt the user to enter the root password on a variable number of serial console devices, in addition to the tra-
       ditional console device. See consadm(1M) and msglog(7D) for a description of how to configure a serial device to  display  the  single-user
       login prompt.

FILES
       /etc/default/sulogin

	   Default value can be set for the following flag:

	   PASSREQ

	       Determines if login requires a password. Default is PASSREQ=YES.

       /etc/default/login

	   Default value can be set for the following flag:

	   SLEEPTIME

	       If  present, sets the number of seconds to wait before login failure is printed to the screen and another login attempt is allowed.
	       Default is 4 seconds. Minimum is 0 seconds. Maximum is 5 seconds.

	       Both su(1M) and login(1) are affected by the value of SLEEPTIME.

NOTES
       By default, the root user has all authorizations.

       Granting the solaris.system.maintenance authorization to the Console User Rights Profile may have an undesirable side  effect  of  granting
       the  currently logged in user maintenance mode access. The solaris.system.maintenance authorization should be directly granted to appropri-
       ate users rather than through the Console User Rights Profile.
