User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.57 Safari/537.17 Steps to reproduce: I (unintentionally) installed beta 19.0. Opened Address Book and pointed it to my company's LDAP server (which had already been configured and working with previous builds). I typed a name in the search bar. Actual results: Thunderbird asks for my password on each search. When I gave my password, the query would succeed. However, there was no "use Password Manager" checkbox on the password dialog, so I would have to enter my password for each query. Expected results: There should have been a "use Password manager" checkbox in the password dialog so that I could avoid typing my password each time. I found some old posts on the internet which dealt with similar problems (missing "use password manager" checkbox), but none seemed to apply or work in my situation. I switched back to the release stream and I installed release build 17.0.2 over top of beta 19. The first time the password dialog came up, it had the appropriate checkbox. I checked the box and verified that the 17.0.2 password manager works for my LDAP server. Note that the password manager was working normally for IMAP and SMTP accounts in beta 19.

Same problem for me since updating to 19.0beta1 on Mac OS X. User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:19.0) Gecko/20130117 Thunderbird/19.0
