Hello,
I am running slapd(openldap-2.3.32) on a linux host. I am also running openldap-2-32-3 on a linux client.
If I use the "allow_bind_v2" switch in the slapd.conf file, I can do anonymous simple binds from the client to the server over TCP with no problems.  I can also do simple login/password authentication with no problems.

I now an trying to use v3 secure connections.  When I attempt to authenticate, I get the following errors from the slapd logs (in bold):

TLS trace: SSL_accept:SSLv3 flush data

My slapd.conf file is:

include         /usr/local/etc/openldap/schema/inetorgperson.schema

It loks to me as is slapd is trying to read the client certificate even though my slapd.conf file entry "TLSVerifyClient never" is set.  I am new to this all, so I do not know if I am interpreting this correctly or not.

Any help would be most appreciated.

Thanks,
