Windows Network Domain

Windows network technology enables you to create network domains. A domain is a group of connected Windows computers that share user account information and a security policy. A domain controller manages the user account information for all domain members.

The domain controller facilitates network administration. By managing one account list for all domain members, the domain controller relieves the network administrator of the requirement to synchronize the account lists on each of the domain computers. In other words, the network administrator who creates or changes a user account needs to update only the account list on the domain controller rather than the account lists on each of the computers in the domain.

To log in to a Windows database server, a user on another Windows computer must belong to either the same domain or a trusted domain. A trusted domain is one that has established a trust relationship with another domain. In a trust relationship, user accounts are located only in the trusted domain, but users can log on to the trusted domain.

A user who attempts to log in to a Windows computer that is a member of a domain can do so either by using a local login and profile or a domain login and profile. However, if the user is listed as a trusted user or the computer from which the user attempts to log in is listed as a trusted host, the user can be granted login access without a profile.

Important:

A client application can connect to an Informix database server only if there is an account for the user ID in the Windows domain in which the database server runs. This rule also applies to trusted domains.

For more information on domains, consult your Windows operating system manuals.

Important:

The Informix trusted client mechanism is unrelated to the trust relationship that you can establish between Windows domains. Therefore, even if a client connects from a trusted Windows domain, the user must have an account in the domain on which the database server is running.
