RE: broken pipe - serious problem with OpenLDAP 2.0.21
Adding my two cents too... if that is in fact the problem, it's probably a
good idea to post something to Redhat's bugzilla site. I've done that a
number of times since my RH install a few months ago, and they often (but
not always) come back with a new package in a day or so if one can provide
enough data to reproduce the problem.

Just my two cents worth...
I recently set up an LDAP server w/Kerberos/SASL authentication. I am using
RH72. It worked nicely with the 2.0.11 rpms, but when I attempted the exact
same install with the 2.0.21 rpms it failed every time, no communication via
SASL to Kerberos. I had originally thought it was incompatibility with newer
LDAP/older SASL, but since then I've heard numerous stories about RH's
2.0.21 rpm not working for various reasons. I would probably place the blame
on that, rather than the LDAP version itself. If you want to use rpms (as I
did) I would recommend using the older version (also as I did).
