Red Hat Directory Server nsslapd-plugin Version, Vendor, Description, pluginID value none, does it matter?

Issue

After a new installation and configuration of Red Hat Directory Server / RHDS 8 on Red Hat Enterprise Linux / RHEL 5, or with RHDS 9 on RHEL6, some information seem to be missing for several plug-ins in the main configuration file, /etc/dirsrv/slapd-ca1/dse.ldif:

nsslapd-pluginId: none
nsslapd-pluginVersion: none
nsslapd-pluginVendor: none
nsslapd-pluginDescription: none

The plug-ins can be:

dn: cn=Account Policy Plugin,cn=plugins,cn=config
dn: cn=attribute uniqueness,cn=plugins,cn=config
dn: cn=IPA Version Replication,cn=plugins,cn=config
dn: cn=PAM Pass Through Auth,cn=plugins,cn=config
dn: cn=Pass Through Authentication,cn=plugins,cn=config
dn: cn=Posix Winsync API,cn=plugins,cn=config
dn: cn=Retro Changelog Plugin,cn=plugins,cn=config
dn: cn=Space Insensitive String Syntax,cn=plugins,cn=config
dn: cn=Syntax Validation Task,cn=plugins,cn=config
dn: cn=URI Syntax,cn=plugins,cn=config

Space Insensitive String Syntax Syntax Validation Task URI Syntax USN For the plugins of these that existed in 8.1 they had values.
Those information seem also to be missing from the DS console.
