-- end of repeat --
My observation is:
1. our AD domain controller locks my account after 3 unsuccessfull logins.
2. When I enter wrong password evolution tries to perform HTTP request on
exchange server about 1000 times.
2a. No error message is generated
2b. My domain account gets locked, this prevents me from being able enter
valid password
2c. Each HTTP request opens a new tcp socket, without closing it
3. The only way how to recover from this state is: "killall evolution; rm -rf
~/.evolution ~/.gconfd" and setup of new account then.
