dear friend,

try to rename the folloing files and try your command again:


_db_lock.share
_db_mpool.share
_db_txn.share

or move them in anther usless directory.

all the best

I am also having this issue.

Since this is a production machine, I can't move these files around without know what the impact would be.. any help in this matter is greatly appreciated.

Thanks!

I'm not sure if this will help, but try stopping the prpasswdd daemon. You can do this with the command:
/sbin/init.d/prpasswd stop

The prpasswdd is basically a performance enhancement, you don't need it on the system. If the problem is that the prpasswdd has this file locked, stopping the prpasswdd may help.

If you then want to restart the prpasswdd you can use the command:
/sbin/init.d/prpasswd start

prpasswd was not running - so I doublechecked, then started it. I still get the same message. Just in case this did something to re-init the pw db, I killed the process again, and still no go.

Any other helpful hints? I'm pulling my hair out here.. Luckily there are only like 3 primary users of this machine, and root can change the users passwords no problem.

Try running authck -a.

[Rick Collette_2]

# authck -a
tsh appears in Protected Password database but cannot be retrieved
with getespwent()
tsh not listed in /etc/passwd, but is in the Protected Password database.

What are the permissions for the /etc/passwd file?

Is the /sbin/ksh shell there?

Do you get any ouput when you run:

edauth -g root

It seems that the system cannot identify the root user.

passwd: /var/tcb/files/__db_lock.share: Permission denied
Change password: root: unknown user.
