User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.36 Safari/537.22 Steps to reproduce: 1. Add a new LDAP directory, with a Bind DN for authentication. 2. Configure compose to use the new directory for searches. 3. Use Address Book or address completion during compose to trigger a search of the LDAP directory. 4. Enter password 5. Search completes successfully. Actual results: During step 4 (enter password), observe that the password dialog has an input field for the password itself, but does NOT have a check box to remember the password. Expected results: The password dialog SHOULD have a checkbox to remember the password. This was present in TB 18, and works there as expected.

This is the behavior on Mac OS X 10.8. It may also be the behavior on other platforms, but I've not upgraded my TB 18 on Linux due to this issue.

That's exactly what is also covered by my bug filed yesterday.
