Title: Could not set LDAP_OPT_X_TLS to LDAP_OPT_X_TLS_HARD

I am trying to upgrade from http  2.2.10 to 2.2.15 . Httpd comes up and runs but I get

[debug] mod_authnz_ldap.c(623): [client 10.19.47.67] auth_ldap authorise: User DN not found, LDAP: ldap_set_option failed. Could not set LDAP_OPT_

X_TLS to LDAP_OPT_X_TLS_HARD

When attempting to connect to the ldap server (ldaps) . I see some very old posts with similar complaints and 1 having to do with php which I’m not using .

Environment is

Solaris 10

krb5-1.8.3

mod_auth_kerb-5.4

openldap-2.4.23

ssl-1.0.0a

httpd 2.2.15

The old environment using  httpd 2.2.10 connects to the same ldap server correctly 

Any thoughts ?
