In some Linux environments, Vector uses the ingvalidpw program to validate user passwords. It is not strictly a part of Ingres Net. The passwords may originate from any local application or from a remote application coming through Ingres Net or the Data Access Server.

Ingvalidpw is used depending on the requirements of the platform where the password is validated. For example, the DBMS Server uses the ingvalidpw program to validate shadow passwords on Linux or to enforce C2 security in some Linux environments.

The ingvalidpam program can be used instead of ingvalidpw to validate passwords through pluggable authentication modules (PAM).

For more information on both programs, see the Security Guide.
