You may want to allow external users, such as customers, subcontractors, suppliers, or joint venture partners, restricted access to your Coins ERP+ system; for example, to update their company details or to view transactions relevant to their company.
In addition to the password security, External User Security in Coins ERP+ provides several additional layers of security according to where the users log in from.
You specify which IP address or addresses are counted as internal addresses; if anyone logs in from a different IP address they are deemed to be an external user.
External users will only be allowed to log in to Coins ERP+ if the Extranet User field on the user record is ticked. This prevents someone being able to log in to Coins ERP+ from outside by guessing the user ID and password of an internal user.
Each user record can have one or more IP addresses specified on it, and will only be allowed to log in from one of those IP addresses.
This means that, for example, you could specify the router address of the company from at which a user works. This allows a user to be tied down to being able to use Coins ERP+ from their place of work but not say from their home ISP. A fixed IP address is required for this. This applies to internal users as well as external users.
For additional control over the access of external users, you can restrict external users to being able to run a specific list of functions. An external user would not be able to run a function that is not on the list of allowed functions, regardless of their individual or group access permissions.
You set up a dummy user which you set security against; the security settings for this user will be applied to all external users. In order for an external user to be able to run a function, both the actual user ID and the dummy user ID must have access to that function.
