(ITS#9021) TLS: can't connect: TLS: hostname does not match CN in peer certificate

I would like to know why Open LDAP behavior was changed where we must have to configure FQDN name mentioned in certificate in order to work LDAP authentication... else TLS start failing.

I am getting below error and I know that I am using IP address of LDAP server in my configuration instead of certificate subject name (FQDN of ldap server)
