Description of Problem:
I've got an LDAP server (M$ Exchange 2000) configured in evolution. It
requires authentication. The first time accessing the server in a session,
Evo prompts for a password and I enter it, making sure to check the
"Remember password" checkbox. After a while, however, when trying to access
the contacts, Evo prompts again for the password and this time it won't
accept it (just keeps saying Authentication Failed and asks for the
password again). I thought it might be an Exchange problem, but ldap_search
still works even in the middle of Evo prompting for the password. If I quit
and re-start Evo, it prompts once and accepts the password (until the next
time this problem crops up).

Steps to reproduce the problem:
1. Add an LDAP (in my case Exchange 2000) server to Evo which requires
authentication. Select "Remember password".
2. After authenticating and accessing the LDAP server once, wait a while
and try to access it again.

Actual Results:
Evo continually fails to authenticate and prompts for the password.

Expected Results:
Evo should never fail to authenticate after the first successful attempt
because I selected "Remember password". At any rate, it should accept the
password when I re-enter it. 

How often does this happen? 
Intermittently, but basically gauranteed to happen eventually (say, after 4
hours) for every session.
