Description of problem:

1. dsidm -D "cn=Directory Manager" ldap://server -b "dc=example,dc=com" account entry-status "uid=user,ou=people,dc=example,dc=com"
   Error: float() argument must be a string or a number, not 'NoneType'

The problem occurs when the Account Policy Plug-In is enabled but no account policies exist or assigned to a user which causes get_attr_val_utf8_l() to return None for limit in status() of idm/account.py

The fix would be a simple one-liner to just skip the check in this case eg

1. Locked indirectly through Account Policy plugin
   if process_account_policy and last_login_time and limit is not None:

or something like that.
