Hi

I think, you can still login from the console with the password.

If you have an id with with sudo root authrity, reset the password
/usr/lbin/modprpw -k root to reactivate

If that is not an option, try logging on the console that is attached to the system and issuing the modprpw command

If that does not work, you will have to reboot the system and come up in single user mode.

If you are prompted for a password in single user mode, then you will have to boot from the install/recovery CD, and go in to the recovery utilities to reset the password

Even if root becomes disabled, it should ALWAYS be allowed to login via the console. The console can be: direct attached serial console ; LAN console ; web console

Attach the console and it will ask for the password. You can then choose yours. You should also try to find how/ why it got disables. .. Did someone tried to login breaching the security.....

Hi Brain;

Check if someone has sudo (root) access or power broker root access. if not,

you need boot the machine in single user mode and change the root password. now if it is trusted machine, while chaning the password it would ask for old password.

if you know the root password, then..

#/usr/lbin/modprpw -lk root

#/usr/lbin/getprpw root (check the output)

if you want to reset the root password, login through single user mode and reset the password.

#cd /tcb/files/auth/r
#cp -p root root.bak
#vi root

delete the entry from u_pwd=:xxxxx:

save and come out

reset the root password with passwd command.

**if your root password is disable u can't login through LAN console***

Hope above information will help u to resolve ur issue.

Cheers;
