If you use an LDAP server with Postbox that uses a self-signed certificate which causes you to get a popup, about a self signed certificate which cannot be trusted every time you use the LDAP server then disable it by doing:
- Go to Preferences | Advanced | Security | Certificates
- Select the Servers tab
- Select the Add Exception button
- For the location, enter the ldap server and the port used for ldap, separated by a colon. Such as: my.ldap.directory.com:636
- Restart Postbox
You should no longer see the popup when making ldap connections.
