Database Manager Configuration Parameter: TRUST_CLNTAUTH

ВысокийУровень 1Автоматическаяdb2

Описание

This database manager configuration parameter is only active when the authentication parameter is set to CLIENT which is not a recommended setting as discussed in the [authentication parameter section](#specify-a-secure-authentication- type-authentication). If the parameter is set to CLIENT, the user ID and password are not needed, but if they are provided, authentication will occur at the ... Passes when the effective connection authentication (SRVCON_AUTH, or AUTHENTICATION when SRVCON_AUTH is NOT_SPECIFIED) is not CLIENT; otherwise TRUST_CLNTAUTH must be SERVER. Run as the instance owner (or with sqllib/db2profile sourced) so the db2 CLP reads this instance's configuration.
