This PR adds support for the
LDAP_OPT_X_TLS_CACERTFILE
option in order to specify a CA file which should be used. It is available since the same PHP version as the other options and may just have been forgotten.Furthermore the connection options need to be applied at different stages in order to be effective.
Connection options are tagged to be preconnect-options and are executed before
ldap_connect
, all other options continue to be applied betweenldap_connect
andldap_bind
.Be aware that there is no LDAP documentation about which option is global and thus not requiring a connection and which needs one.
The preconnect options from this PR come from trial-and-error testing and mailing list entries at OpenLDAP.
