安装VC好几天，想管理，但却忘记了密码，这下大发了。

于是，GOOGLE一番，找到官方网站，有如下解：

• In emergency situations or if the default policies have been changed, you can also reset the password to unlock the account. 
  To reset the SSO administrator password on a Windows server:
  Note: Resetting the password will also unlock the administrator account.

1. 1. Login as an administrator to the vCenter SSO server.
   2. Click Start > Run, type cmd, and click OK. The Command Prompt window opens.
   3. Navigate to the directory SSOInstallDirectory\utils. By default, the installation directory is  C:\Program Files\VMware\Infrastructure\SSOServer\utils.
   4. Run this command:
      rsautil reset-admin-password
   5. Enter the master password when prompted.
      Note: This is the password selected for the SSO administrator during the SSO installation. If you have changed your SSO administrator password later, the master password is still the original one chosen.
   6. Enter the SSO administrator name for which you want to reset the password. For example, admin.
   7. Enter the new password for the user and then confirm it a second time.
      You should see the message Password reset successfully.

巴特！！！！！！！！！当我按这个操作时，它却需要我先输入 master password，，，XXXXXXXXX，这显然也在我记忆之了。这时，好希望《盗梦空间》里的高手出现，接收我遗失在潜意识深处的脑电波。。

整理心绪，重装上阵，天南海北的翻遍互连网时，

发现一个线索贴：

For 2008 R2, you can check the following location and see if the password listed here jarrs your memory:

"C:\Program Files\VMware\Infrastructure\SSOServer\webapps\lookupservice\WEB-INF\classes\config.properties"

Note:  Afterall, I think the above is just the sso db pw but if you set everything the same it could be an instant win.

If this was an upgrade to 5.1 and now you can't login, you may consider reviewing the list of valid admins from "vc_admin_users_groups.txt" (if based on your scenario one populated for you).  It would be in the temp directory of the person performing the upgrade (i.e. Start > Run > %tmp%).

Folder Location:

C:\Users\<xyzuser>\AppData\Local\Temp

valid admin list: vc_admin_users_groups.txt

Admins that were removed:

deleted_vc_users.txt

Once you get an ID that you can login into the vSphere C#lient with, go to the permissions tab of the root datacenter for example, and add the appropriate groups that SSO took out (i.e. your server team or whatever).  Then login to the web client / sso related stuff.

依葫芦画瓢。。。。LOOK。。。DB.PASS。。。明文哟。。

得此密笈，再循回刚才要输入重置密码之处，搞定！！！（PS：小注意新密码也要符合其复杂度）

然后，，VSPHERE CLIENT,WEBCLIENT,重见光明。。。
