Severity: 3-Major


Attempting to set a password to the current value of its encrypted password silently fails without changing the password. For example, running the following tmsh command sets the encrypted password to the value 'password': modify auth user <username> encrypted-password password Attempting to set the password to 'password' using the command does not report an error, but does not change the password (meaning that encrypted password remains 'password'): modify auth user <username> password password


Difficult to recover from this situation because trying to simply change the password to the correct value doesnot work. (It is likely this initially happened by accident: attempting to set 'password', but setting 'encrypted-password' instead.)


Changing a password to the value of encrypted-password.


First, change the password to something else. Then, change it back to the correct value.
