[Dovecot] Password prompt

[Zachary Schneider]

When checking multiple POP3 accounts against Dovecot + ldap AUTH with 
outlook XP and Mail.app password dialogs randomly request that you 
reenter the password.

I see stuff like this in the logs:

Feb  4 19:02:25 geonosis dovecot: login: received another "not 
listening" notification (if you can't login at all, see 
src/lib/fdpass.c)
Feb  5 08:53:19 geonosis dovecot: login: received another "not 
listening" notification (if you can't login at all, see 
src/lib/fdpass.c)

and:

Feb  4 12:00:41 geonosis pop3: I/O leak: 0x8050cc0 (0)
Feb  4 12:00:41 geonosis pop3: I/O leak: 0x80848d0 (1)
Feb  4 12:02:05 geonosis pop3: I/O leak: 0x8050cc0 (0)
Feb  4 12:02:05 geonosis pop3: I/O leak: 0x80848d0 (1)

and:

Feb  4 11:35:02 geonosis dovecot-auth: Login process has too old (125s) 
requests, killing it.
Feb  4 11:35:50 geonosis dovecot-auth: Login process has too old (123s) 
requests, killing it.

This is the most recent version of Dovecot.
IMAP appears to work pretty flawlessly.

Please advise
Thanks
