I've got an LDAP server configured for in Thunderbird's address book (ldap.example.com). I'd like to use the SSL version, so I checked the 'Use SSL' box. It starts to work, but I get a certificate warning in response. Okay, sure, I know that server uses a funny certificate, so I'll add it.
I found the 'Add Security Exception' box readily enough, and it asks me for a server location. But I don't know what to put in there. The dialog box starts with https:// in it, but https://ldap.example.com doesn't work, and neither does anything like imaps:// or ldap:// or ldaps:// (is that a real protocol name? well, I tried it). LDAP really is the only service this server provides.
How can I get Thunderbird to read the certificate?
