Re: SSL Client Certificate Error with v3 but not v2 using LDAPS

Thanks for the all the help.

What we discovered is that the LDAP server (Oracle Directory Server 6.3)
had client-auth set to "allowed" rather than "off" and GlassFIsh 3 and its
KeyManager seems to send the cert in this case. When it was changed to
"off" then the cert isn't sent and things work.

So, is the correct behavior for the KeyManager to send the cert when the
setting is just "allowed" rather than "required"? Is there some config or
a setting we can use to disable sending the cert when it is "allowed"?

We are also going to look into getting a valid cert that the LDAP server
will trust which should solve it too.
