In the versions of VMWare ESXi 5.x servers, when changing the root user's password, I have entered blank spaces, the system has not given any errors, but from that moment, I could no longer log in with the root user, through of any tool. It always gives an invalid user error or password.
In the rest of the users, it admits the blanks and I can enter without problems.
With this, several questions arise:
- In the root user's password, is the white space changed by any symbol?
- Are blank spaces ignored?
- Is the password invalid and therefore the root user?
