Hello,

After compiling OpenLDAP 2.1.3 with Cyrus SASL 2.1.5, I continued to encounter
the behavior I had seen previously of slapd having a segmentation fault whenever
I used GSSAPI authentication.  I finally did a truss on slapd while it was
running, and discovered that the problem is that slapd is essentially ignoring
my krb5.conf file in /etc/leland (the location we store it in at Stanford), and
trying to instead use /usr/local/etc/krb5.conf.  Once I put a link in, slapd
works fine, and GSSAPI authentication proceeds without problem.  Here is the
pertinent bits from truss:
