[389-users] Cannot set nsslapd-dncachememsize with dsconf

Hi,

I am trying to set nsslapd-dncachememsize to a bigger value using
dsconf. I am following the steps from here:
https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/8/html/tuning_performance_in_identity_management/adjusting-idm-directory-server-performance_tuning-performance-in-idm#adjusting-the-dn-cache-size_adjusting-idm-directory-server-performance

But when I check the size afterwards using ldapsearch I get the previous
size and not the value I set it to.

I have read the note at the top of the documentation about only changing
the value if necessary, but I am running into this error
https://access.redhat.com/solutions/3098131 and the fix suggests
changing the value.

Thanks in advance
Julian
