Unable to reset administrator@vsphere.local with vdcadmintool (failed 9100)

[Sepiroth23]

I'm trying to reset the administrator@vsphere.local password but it fails every time...

I'm using this document : VMware KB: Cannot change the administrator@vsphere.local password after upgrading from vCenter Serve...

But everytime I try it fails with code 9100:

Here is my log:

==================

Please select:

0. exit

1. Test LDAP connectivity

2. Force start replication cycle

3. Reset account password

4. Set log level and mask

5. Set vmdir state

==================

  Account DN: cd=administrator,cn=users,dc=vsphere,dc=local

VmDirForceResetPassword failed (9100)

Anyone know how to fix this ??

Try running command as su.

vGeek: Reset administrator@vsphere.local account password on vCenter appliance

[Sepiroth23]

Forgot to mention that we aren't running the appliance.

So I can't run the command as "su".

Could it be a version related issue ?

vCenter Server = v5.5.0.39885 (vCenter is running on Windows Server 2012)

PowerCLI = v5.5.0.6296

just run

su -

it will ask for password and you will be in superuser mode. they you can try the command

[Sepiroth23]

As mentioned above, I'm not using the appliance.

I'm working from an elevated prompt on a Windows 2012 server that doesn't have a "su" user .

So, running the task as "su" isn't an option.

Had the same issue today, the solution is simpler than it looks at the beginning. Made following two mistakes :

1. The first attempt was wrong, because there were spaces left after the commas (cn=administrator,"space"cn=users...)

Account DN: cn=administrator, cn=users, dc=vsphere, dc=local

VmDirForceResetPassword failed (9100)

2. The second attempt was wrong, because there was entered "cd=administrator" instead of "cn=administrator" :

Account DN: cd=administrator,cn=users,dc=vsphere,dc=local

VmDirForceResetPassword failed (9100)

When entering the correct words without spaces, everything ran fine :

Account DN: cn=administrator,cn=users,dc=vSphere,dc=local

New password is -

Hi Everyone,

I have done the same in windows based vCenter 6.0 U2

I have logged in vcenter machine as local administrator and done the remaining tasks as you have mentioned. the issue got resolved. Try the same.

Same issue here, finally just did a full reinstall.  vCenter 6.5 has some major account management issues.  It was a fresh install and the password I submitted simply didn't work.  And of course the password reset procedure doesn't work either.

You need to run the tool as an Local administrator
