SULOGIN(1M)SULOGIN(1M)NAMEsulogin - access single-user mode
SYNOPSISsuloginDESCRIPTION
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 (typi‐
cally CTRL-D) for normal startup (multi-user mode). The user should
never directly invoke sulogin. The user must have the solaris.sys‐
tem.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 tradi‐
tional 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.

SLEEPTIME

TIME.

msglog(7D)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.sys‐
tem.maintenance authorization should be directly granted to appropriate
users rather than through the Console User Rights Profile.
