Yes, disabling PAM only disables the user auth component.

[Bug 302026] Re: likewise-open prevents local passwords from being changed

[kc77]

I ran into this on 9.10 server and I am using the likewise that was
within the repositories. Unfortunately this needs to be fixed as within
server environments DNS is usually disabled for those machines outside
of the domain. Thus joining them to the domain is relatively routine.

Disabling PAM only disables user auth against AD is that correct? If so
the machine should stay within the domain even though user auth is
disabled. Can you confirm?

[Gerald Carter]

This doesn't seem to have any real relevance to the original bug report.

You installed packages from likewise.com right?  And then upgraded the
ubuntu 9.04 workstation to a newer ubuntu release?  In any case, boot
into single user mode and run the following as root:

  $ /opt/likewise/bin/domanjoin-cli configure --disable pam
  $ pam-auth-update -f (and accept the defaults)

When you are comfortable with the upgraded system, you can run the
following to re-enable the pam_lsass module.

  $ /opt/likewise/bin/domanjoin-cli configure --disable pam

Please note that I realize this is not very Ubuntu-like to modify pam
files directly.  There's an upstream bug report already.  The native
ubuntu packages (in main/universe) do the right thing however.

[Adrian Moya]

Hi guys, I'm having this problem on several ubuntu 9.04 workstations
using likewise 5 package from likewise directly. I cannot do sudo
anymore after an upgrade. This workstations are in production and I'm
out of ideas, could somebody explain to me what's the workarround to
this issue? Is it possible to repair the main local user authentication?
I have asked for help in likewise forums but I'm running short on time.

Thanks!

It must be 4 as the version 5 in the karmic repository can't be joined into
a domain due to a kerberos change.

5.4 direct from Likewise works though (in a vm).

I think I am seeing this issue on Karmic.
I have likwise installed, and I am unable to change my password.

Using "users-admin"->"Properties"->"Change Password" locks up when 
authenticating, with the message"Checking Password".
Using "passwd" gives me "passwd: Authentication token manipulation error".

im using  4.1.2982-likewise-1 on ubuntu 8.10 server
not only that it does not allow to change local password it also crashes and 
its not usable at all.
ubuntu should fix the problem on 8.10 since its a bug and not a new version.

That is exactly what happened to me.   Save versions etc.

Basically there will not be a fix.  Likewise 5 is not supported on ubuntu
8.1...

I am still having no issue with Likewise 5 on Ubuntu 9.04.   Am awaiting the
first pam update though with some nervousness as I believe that this was
what caused my issue.

Will make sure I take a full backup of /etc before applying any updates.

I am also having this issue, but passwd doesn't give me the password

# passwd allen
passwd: Authentication token manipulation error
passwd: password unchanged

If I comment out the entries containing /lib/security/pam_lsass.so from
common_auth, common_password, and common_account, I can change passwords
and su to local users, but I can no longer authenticate my domain
account, which was expected.

This problem started occurring after running update.  When I first

domain or local accounts.

Not sure it will.  I was using likewise 5 (package sourced from likewise not
ubuntu) on Ubuntu 8.04 which was not supported by Ubuntu at the time.

I reinstalled everything and am now running likewise 5 on 9.04.Have had
no issues so far.   Likewise 5 is now in the Ubuntu repositories so if the
problem re-occurs it should be easier to get a resolution (without resorting
to a reinstall).

I confirm this bug on kubuntu 8.10 and on current jaunty (as of today's date).
I didnt realise it was due to likewise install
1) After editing the common-password file i was able to change passwords fine :)
2) I have also installed libpam-cracklib to make sure a new update doesn't 
recreate the problem

thanks for the pointers ;)

I thought that might be the answer...

The Ubuntu release is 4.x and the Likewise release is 5.x

I will try removing myself from the domain uninstalling and then
reinstalling ...   But will wait until closer to Xmas in case I end up with
a non-functioning computer.

[Bug 302026] Re: likewise-open prevents local passwords from being changed

[Buddha]

I should have said, everything seemed fine with local user access until today.

Today I did updates and installed vmware server, before I found I could
no longer log in using a local account.

Ubuntu 8.10/AMD64.  Likewise Open was installed using the DEB from
likewise rather than the repository version.

Now I don't believe it is vmware that has caused the issue, more
probably the updates I received.

vmware is having its own issues of course due to a keyboard mapping
issue in Ubuntu but this seems to be a known bug with a workaround that
hopefully will work tomorrow when I am back at work.

I have now got access to root by adding my domain users group to the
sudoers file so I can manage.

Everything was good in 8.04.   I just needed to change to 64 bit...

Let me know if you need more info and how to get it...

I also ran into this issue... but with even more dire results.

I can login with domain accounts, but not local accounts.  Even the
local admin account no longer works which means I can't even get

If I boot with

and then try to reset the local admin users password I get

[Bug 302026] Re: likewise-open prevents local passwords from being changed

[Steve Langasek]

The reason for reusing the passwords between modules is to ensure the
user is only prompted for a new password once.

There is no "try_authtok" equivalent to "try_first_pass", and special-
casing pam_lwidentity in pam-auth-update would not be a good idea.  I
think pam_lwidentity needs to prompt for and store the new password,
even if it won't use it itself, otherwise there's no way for us to have
a completely pluggable stack.

Also, if the return code here is "password updated successfully", then I
think that implies pam_lwidentity.so is incorrectly returning
PAM_SUCCESS for users it doesn't know about.  It shouldn't do this - it
should return a sensible return value that lets the administrator
construct a useful stack, instead of presuming that PAM_SUCCESS is
wanted.

BTW, installing pam_cracklib may (or may not) work around this.

[Bug 302026] Re: likewise-open prevents local passwords from being changed

[Thierry Carrez]

Confirming...
Once likewise-open is installed (whether a domain is joined or not), running 
"passwd" to change a local password fails: it never prompts for a new password. 
(Changing a domain password works.)

It also always returns "passwd: password updated successfully"

I suppose there is something wrong in the PAM stack:
password[success=2 default=ignore]  pam_lwidentity.so 
password[success=1 default=ignore]  pam_unix.so obscure use_authtok 
try_first_pass sha512
passwordrequisite   pam_deny.so
passwordrequiredpam_permit.so

use_authtok forces pam_unix.so use the password entered for
pam_lwidentity.so... but if the user is not in the domain there is no
such token. There is little to gain in reusing passwords between
pam_lwidentity.so and pam_unix.so, since they aren't targeting the same
users...

As a dirty workaround "use_authtok" can be removed from 
/etc/pam.d/common-password:
password[success=1 default=ignore]  pam_unix.so obscure use_authtok 
try_first_pass sha512
(that change will be overridden next time pam-auth-update is run)
