Check against OpenLDAP 2.4.25. I believe nearly all backends and
overlays support slapd-config now.
I'm using 2.4.25, but short of trying every one of the official and
contrib overlays one by one, I don't know of any way to find out which
ones don't support slapd-config. That's why I was asking: I was hoping
someone knew what the holdouts were, or knew where it was documented.
I meant more, use the source. From what I can tell, overlays with no
cn=config support are:
They also don't have manual pages, so probably aren't exactly supported
They have no config settings at all, therefore they work regardless of static
or dynamic config. At this point it's more useful to ask "which don't work
with dynamic config" than "which support dynamic config". There are several
overlays that need no configuration.
Between that and the -devel note about backends, I think you can create a
- Admin Guide, chapter 21. The tuning chapter doesn't mention the
potential benefits of using sysv shared memory vs. mmap'ed files on
some platforms. Should it? Same offer for documentation patch applies,
though I expect this one will need more feedback from the experts.
Do you mean the shared memory keys, or something else?
The shared memory keys.
Definitely worth noting. It is a requirement for Solaris if you want any
sort of decent performance.
Apparently it's become more important on recent Linux kernels too.
