imapsync works to the zimbra admin user, but not others?

[justanotheruser]

Hi -

I got imapsync working when it's from whatever account, to the admin account on our zimbra server like so:

imapsync --nosyncacls --subscribe --syncinternaldates --host1 mail.vivid.com --user1 jenna --password1 jameson --authmech1=LOGIN --host2 zimbra.vivid.com --user2 admin --password2 theadminpassword --authmech2=PLAIN --ssl2

.. but if I try to sync up accounts to a non-admin account it doesn't seem to work:

imapsync --nosyncacls --subscribe --syncinternaldates --host1 mail.vivid.com --user1 jenna --password1 jameson --authmech1=LOGIN --host2 zimbra.vivid.com --user2 tera --password2 patrick --authmech2=PLAIN --ssl2

and I get:

Error login : [zimbra.vivid.com] with user [username] auth [LOGIN] : 3 NO LOGIN failed

Does the user actually exist on the Zimbra server?

yes, the user(s) already exist(s) on the source and target servers, which is what is strange.

Just a shot here, I noticed you're specifying PLAIN for the login mechanism. Have you in fact enabled that on the server??
