My "surprised" comment is in reference to the fact that the default
build of OpenLDAP only supports SHA1, which is widely regarded as
deprecated. Why hasn't the sha2 module been migrated out of the
contrib directory is what I am getting at (which commonly requires
situations like this -- forcing people who wouldn't otherwise do so to
install from source just to obtain this feature). One could argue that
situations like this contribute to the lack of adoption of stronger
password schemes in general. Something of an off-topic tangent.

Great. I will investigate.
Does anyone else know of any yum-compatible repos that have a
sha2-enabled OpenLDAP build in them? Anyone know anything about the
OpenLDAP packages in RepoForge?
I actually only assumed without testing that the OpenLDAP package in
the CentOS base repo doesn't have the sha2 module compiled in. I
should go back and check that assumption.
Also, reflecting on the installation of the sha2 module, it occurs to
me that short of the CentOS repo package already having sha2 compiled
in, the best course of action is probably to compile only the sha2
module and use it with the CentOS package --- including the module in
the slapd configuration seems to be the extent of integration, so that
should work, no? If so, I think this would be the best option.

I'd welcome pointers to somewhere this is discussed (don't see it in
the docs, maybe in the FAQ?). I don't have needs that are much
different than anyone else.
I naively assume slapd should generally not be run as root. In that
case, is creating a ldap user/group and chowning the openldap-data
directory the only things to do?

I'm looking for anyone who wants to share such scripts.
Thanks kindly for your time, much appreciated.
