I have a stand alone Solaris 9 system, I am able to log in as root, when I try to run Solaris Management Console 2.1 to create/delete/modify users it prompts for the root password. I enter the root password and it doesn't take and prompts again to enter the root password. Current encryption is MD5, current password is 14 characters long, changed to 8 characters still same issue. Not sure exactly where to look or what I should be looking for, other information I have gathered if it helps:
Seems your root password is not working.
Boot the system with CD to single user from PROM (ok).
From OK prom issue boot cdrom -s, the system will boot to single user mode.
Mount your root device, it will be something like /dev/dsk/c0t0d0s0, mount it to some mount point like /mnt or /a. (mount /dev/dsk/c0t0d0s0 /mnt)
remove the encrypted password for user root and save the file.
umount /mnt or /a where root partition is mounted.
reboot the system and re-set your root password using passwd command.
