Full Discussion: unable to login Solaris 10
Operating Systems Solaris unable to login Solaris 10 Post 302493552 by Sol-nova on Thursday 3rd of February 2011 04:40:28 AM

[SOLVED] unable to login Solaris 10
I have inherited a solaris 10 server. I went to log into it the other day over the console connection, and after sucessfully entering the password, I was booted back to the login prompt with no errors visible.

If I enter an incorect password, the console displays 'incorrect password' and kicks me back to the prompt. A correct password does not display this error but still kicks back to the login prompt. A hard reboot (hitting the power button) does not resolve the problem, and there are no errors apparent when the machine is booting.

I did not set up the server and i have no idea what the guy before me did to it, he has now left. Any thoughts on what could be wrong?

I considered a full HDD but could not recreate the problem on a virtual machine? I would also expect more errors on the boot sequence if the disk were indeed full.

Thanks in advance

sulogin

sulogin(1M)						  System Administration Commands					       sulogin(1M)

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.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWcsr			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       auths(1), login(1), consadm(1M), init(1M), su(1M), attributes(5), 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.system.maintenance authorization should be directly granted to appropri-
       ate users rather than through the Console User Rights Profile.
