Red Hat statically links nss-ldap.  That explains a lot.  I bet they're
just living with all the other (less common) library conflicts.  I wonder
if they statically link pam-ldap as well, since that's the other major
source.

(Thanks to Quanah for the investigation.)

So, the other thought that occurred to me: what if libldap and libldap_r
both had symbol versioning with different versions?  In that case, they
should be able to share process namespace with each other, which would
avoid the problem of libldap getting sucked into slapd's namespace via,
say, back-perl and would also let the problems of any package that chooses
to link directly to libldap_r be only the problems of that package and not
more general library conflict problems.
