OK. I had the old cert in there.
I followed the instructions and did a
cp cacert.asc /etc/openldap/cacerts/`openssl x509 -noout -hash -in
cacert.asc`.0
and set TLS_CACERT to /etc/openldap/cacerts/cacert.asc. I still get the
same error
[02/Jun/2006:15:24:47 -0700] conn=10 fd=67 slot=67 connection from
127.0.0.1 to 127.0.0.1

nentries=0 etime=0
[02/Jun/2006:15:24:47 -0700] conn=10 op=-1 fd=67 closed - Peer does not
recognize and trust the CA that issued your certificate.
