Secure SSL/TLS access to LDAP and DAV now mandatory

Over the last few years we’ve been phasing in mandating SSL/TLS encryption on all connections between user machines and our servers, ensuring that no one can eaves drop on your username or password to steal your login credentials.

We’re continuing with that process today by disabling non-SSL/TLS access to all LDAP and DAV services. We emailed everyone we believe that was using these services a few weeks ago to inform them of the upcoming change.

This means if you use LDAP to access your address book, you must use port 636 with SSL/TLS enabled.

If you use DAV to access files in your file storage, you must use https://dav.messagingengine.com, not
http://dav.messagingengine.com (note the additional “s” in https://).
