TLS LDAP and CalDAV

[asctime]

Here are a few notes on getting LDAPS working, with modern encryption.

• Server certificate MUST be recognized by the operating system.
  (We can download the certificate and convert to DER (.crt) format directly, using openssl.)
  (Install the certificate in Windows using certmgr: Often you must "Browse" -> "Show physical locations" and save to "Trusted Root Certification Authorities\Registry" for it to work)
  Evolution will not prompt to add an ad-hoc certificate for LDAP or CalDav as it does email images etc.

• LDAPS TLS-elevation does not seem to work from the plain-text port (389)

• LDAPS using TLS 1.x full-time encryption does work if port is specified as 636
