Can't change password in Trusted system

Chris Fung — Wed, 16 Jan 2002 08:00:24 GMT

Hi,

After I enable the trusted system through sam in my L1000 machine which running HP-UX 11.0 (64-bit), I cannot change the password for any account even root. I only got the error message "Unexpected failure, Password file unchanged" after I issue the command > passwd [account name]

I tried to open another terminal to login to the system, but even I provide the correct password, the system just won't allow me to login. Now I only got a running session left!! And I am afraid I could not login again with any account after I close this session. Pls help!!

By the way, I counldn't locate the restore command for tcb both in command line or in SAM.

Thanks for help,

Chris Fung,

Hi Chris,

You need to un-trust the system first.

# /usr/lbin/tsconvert -r

These commands do not have on-line
man pages.

Hi,

In case you want to go back :
/usr/lbin/tsconvert -r
That will restore your old /etc/passwd and /etc/group as it was before in non trusted system.
Then, chack if you have the latest HP-UX Patch for passwd/add/mod/delete and SAM Patch :
PHCO_20679 (user/group add/mod/del)
PHCO_20187 (SAM)
PHCO_24189 (passwd)
PHKL_24276 (trusted system)

It may help

Hi,

If you wished to try this again, your
will need to change your 'root'
password. (after) I use sudo on all of my
systems, so I don't need to use this....
Anyway to trust your system use

# /usr/lbin/tsconvert
to convert back use -r
In the link below are man pages where
you can administer some of your trusted
system. Just a word of caution... If you trust
a system all users will need to change their
passwords.... Watch out for potential
mutiny... The best method is of course to
trust a system during the initial build
stages.

Use the modprpw -k to unlock
accounts.

It sounds like the process to convert to a trusted system didnt work properly. Did you use SAM to convert it ? (I presume so seeing as you couldnt find the tsconvert command). So do you have the latest SAM patches ? Theres always patches coming out for it. I make the latest; PHCO_23876

Try to get your system back to how it was (/etc/passwd looks good, can login aok etc. make sure the /tcb directory is not there or rename it) then update your patches and retry. There is no particular patch for the tsconvert command.

Hi,
Try this

#/usr/sam/lbin/usermod.sam -F -p "" root
#passwd

Password should not be more than 8 chars.

Best of luck

Hey guys,

I tried to reconver my system to tcb again and I found that there was an error message generated after I issue the password command for an normal user account:

Quote

>passwd xxx

Changing password for xxx
Last successful password change for xxx: NEVER
Last unsuccessful password change for xxx: NEVER

Current user has no Protected Password Entry

>

Unquote

What I am wondering is that, the last message - "no protected password entry" What's going on for my machine? I got all the patches mentioned-above except PHCO_20187 which I couldn't find it in patch database as well !!

Any recommendations for implementing the tcb are appreciated.

Chris,

Hi

Sounds like an entry in passwd not in protected passwd

Try Running ' /usr/sbin/authck -pv '

Correct any problems
