What happens if you disable both LDAP and cache support from NSS before
upgrading either of those two packages?  Installing files certainly must
invoke functions that need to translate owners/groups to uid/gid so perhaps
something related to that suddenly fails during an attempt to replace
the library.  It sounds like if your LDAP support becomes corrupt, then
it leaves a gaping hole in the NSS critical path that many parts of the
system must be using.  When you run into this situation and can resolve
it easily by replacing the old ldap library, is the old one corrupt?
Missing?  Can you save a copy for evaluation?  Does your system break in
a similar manner simply by renaming the LDAP library, or does it behave
worse only if there is a faulty LDAP library being used by nss_ldap?
