Invalid Format Message When Creating or Changing a User Account Password Using VI Client

Details

The characters you use when creating or changing ESX Server 3.x user account passwords through VI Client or a third-party management client must meet certain criteria. The password you choose must contain only the following character types:
  • Alphanumeric Characters — You can use numbers, uppercase alphabetic characters, and lowercase alphabetic characters.
  • Special Characters — You can use any of these characters:

    ~!@#$%^&*()_+{}|:"<>?/.,';\][=-`)

    If you create or modify user passwords using characters other than these, the management client displays an error message stating that the user name or password has an invalid format.

Solution

To create a user account that uses characters other than the valid characters described above, create or modify the user account password directly on the ESX Server host using the passwd command. This method might allow more characters than listed above, depending on the password algorithm in use for the host.
