Description

Mitigation
On 389-ds-base 1.3.1 and above: 1- Deactivate clear password storing by default, to prevent new passwords to be logged. -> in cn=config, set nsslapd-unhashed-pw-switch attribute to 'off' or 'nolog'
2- Trim changelog to ensure currently stored passwords are removed. For Replication: -> in cn=changelog5,cn=config, reduce nsslapd-changelogmaxentries, nsslapd-changelogtrim-interval and nsslapd-changelogmaxage -> force a replication & wait for the changelogtrim-interval time -> restore previous values
For RetroChangelog: -> deactivate the plugin -> restart directory server -> reactivate the plugin -> restart directory server
