New submission from Thomas Arendsen Hein <thomas at intevation.de>:

Separated from kolab/issue2855 (Can create folder while logging in as user
without domain name):

Given an account:
 primary email: user at example.com
 uid: unique or uni at que
logging in to cyrus is possible with:
 user at example.com (ok)
 unique/uni at que (ok)
 user (bad)

When the account has a uid with an @ sign (uni at que), signing in with the uid's
localpart isn't possible, so this issue is only related to the primary email.

imapd.conf man page states:

       virtdomains: off
            Enable  virtual  domain  support.   If  enabled,  the user's
            domain will be determined by splitting a fully qualified userid at
            the last '@' or '%' symbol.  If the userid is unqualified, and the
            virtdomains option is set to "on", then the domain will be
            determined by doing a reverse lookup on the IP address  of  the
            incoming network interface, otherwise the user is assumed to be in
            the default domain (if set).
        Allowed values: off, userid, on

virtdomains looks like it could cause this problem, it is set to 'ldap' on Kolab
servers, which is not documented here.
