How to fix?

There is no fixed version for RHEL:7 389-ds-base.

NVD Description

Note: Versions mentioned in the description apply only to the upstream 389-ds-base package and not the 389-ds-base package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in 389 Directory Server. During SASL PLAIN authentication, the server installs connection-level bind credentials before performing the account-lock check. If the account is subsequently found to be locked, the bind is reported as failed to the client, but the already-installed authenticated state on the connection is not reverted. A client that supplies valid credentials for an account that has been administratively locked can continue to use the same connection with that account's privileges, defeating account lock as an access-revocation control.
