Remote User Authorizations
Connection data alone is not sufficient to access a remote Ingres instance. You must authorize users to access the remote instance.
A remote user authorization consists of either of the following:
An Installation Password
An Installation Password enables the user to access the remote instance directly. Users retain their identity as defined on the local instance.
If an Installation Password is defined, a login account is optional.
Login account and password
A login account (set up by the system administrator) on the host machine of the remote instance. Users take on the identity of the login account through which they access the remote instance.
The main advantage of using an Installation Password is that users on the local node do not require a login account on the remote instance’s host machine. They can access the remote instance directly provided they are recognized as valid Ingres users on the remote instance.
Note:  Installation passwords must be used only when user privileges are the same on both local and remote machines. Using installation passwords between machines with different access privileges can lead to security access violations. For example, if a user is able to access the Ingres administrator account on a client machine but not on the server machine, use of installation passwords allows the user to bypass standard security and access the database as the Ingres administrator through Ingres Net.
Ingres Net requires the following remote user authorization information:
Name of remote login account (if applicable)
Password (either a login account password or an Installation Password)
