Thanks for the suggestion.  I ran the strace with both the new, problematic 
nss_ldap, and the old version that works.  I find three places where broken 
pipes result.

Since this is obviously not an SL specific issue, I'm moving my debugging off 
the list.

It looks like this is already reported as 
https://bugzilla.redhat.com/show_bug.cgi?id=447881
No solution yet, though.
