Fallback login option for LDAP

Presently there is no way to log into a Zabbix system configured to use LDAP should the LDAP connection fail. Other programs setup a "fallback" login which is used to log into the system with the same credentials as the administrator should LDAP fail for whatever reason.

Needless to say, LDAP is failing to work with my Zabbix instance and since I'm configured to use LDAP I cannot log in to change the LDAP settings. The only way around this is to directly manipulate the confg db table.
