Full Discussion: Root login does not prompt for password

Root login does not prompt for password
I've an LPAR set up on a P690. The LPAR ran AIX v5.2. I then did an upgrade (using the migration option) to AIX v5.3. I've now encountered the problem that, at the console, I cannot log in as root (or as anyone else that matter). I get the login prompt, enter "root " and then the shell returns to the login prompt.

I get the same result if I enter any other defined user name. If I enter a non-existing name, then the shel prompts for a password and then returns the unkown user/password error.

I've tried going via maintenance mode and using the "passwd" command to reset root's password but this did not work.

Any suggestions?

LEARN ABOUT POSIX

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 the root 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  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.
