User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release) Build ID: 20131206145143 Steps to reproduce: Enter settings for an LDAP server, set one account to use that server for addressing. I'm not sure whether my settings are bad or Thunderbird is broken, because I'm not getting any error indication. Actual results: When adding recipients to a message from the LDAP-enabled account, I can type 2-3 letters before Tbird freezes for several seconds and the rest of my Thunderbird panes turn grey. If I go to Directory Server Properties > Offline > Download Now, I get "replication failed" after a minute or two, but there's no indication anywhere that I can see as to *what* failed. Expected results: Thunderbird should either connect or give me an error that gives some kind of clue as to why the LDAP connection has failed.

Turned up LDAp logging, per https://wiki.mozilla.org/MailNews:Logging and I have this: 2014-01-13 18:50:07.789001 UTC - 253085504[7f900de55370]: unbinding 2014-01-13 18:50:07.789104 UTC - 253085504[7f900de55370]: unbound 2014-01-13 18:50:08.120380 UTC - 253085504[7f900de55370]: Resolving host [machine.example.edu]. 2014-01-13 18:50:08.120444 UTC - 253085504[7f900de55370]: Using cached record for host [machine.example.edu]. 2014-01-13 18:50:08.124052 UTC - 253085504[7f900de55370]: Checking blacklist for host [machine.example.edu], host record [7f8fcf928b80]. 2014-01-13 18:50:08.133387 UTC - 253085504[7f900de55370]: nsLDAPOperation::SimpleBind(): called; bindName = 'moreia@machine.example.edu';

If not resolved when bug 931482 or bug 906663 are resolved, then please reopen.
