Yes, the pam_authc_ppolicy option is used to disable requesting that
control, see
https://arthurdejong.org/nss-pam-ldapd/nslcd.conf.5#pam_authc_ppolicy

While the option was added in 0.9.7 it was non-functional until it was
fixed in 0.9.12.

The missing control logged by the LDAP server should not be harmful in
any way because it is marked as not critical which means it is just a
warning that can be ignored.

I doubt this would be severe enough an issue to warrant an update for
bullseye.
