Description Cedric Buissart 2021-07-15 17:12:44 UTC 
It was found that invalid password hashes were not correctly handled by 389-ds-base.

Asterisks, '*', is a method that can be used in NIS database, or /etc/shadow, to disable an account's password. As a result of the flaw, if an LDAP admin imports such an account from a NIS or /etc/shadow database into Directory Server, any password will be valid for that account.
