    user-accounts: Fix password check when using LDAP
    
    Usually, passwd exits with an error if the current password is incorrect,
    however, when using LDAP, it askes for password again. It causes hangs as
    the passwd helper assumes that the password is correct. Let's prevent this
    hangs using additional check for "incorrect" keyword.
    
    Based on a patch from https://launchpad.net/bugs/607357 made by Ryan Tandy.
