openSuSE 13.1: Help needed with Cyrus imapd


In order to get the other half of my mail server up and running (Postfix works the way it is supposed to now), I’m attempting to get Cyrus imapd up and running - however, there are some obstacles that I need to solve.
Unfortunately googling around always presented me some instructions that are either incomplete (some crucial information is absent) or list particular steps that are impossible to perform right now, which in turn has me going round and round in circles.

First of all, I’m in need of the following information:

  • Where is mkimap located?
  • How do I set up SASL (pwcheck_method: auxprop) to make it access Postfix’s pw database for IMAP authentication? Generating a file imapd.conf in /etc/sasl2 doesn’t seem to help, and imapd.conf is lacking an auxprop_plugin parameter.

Right now a login to the server is impossible (uninitialized authentication mechanism), and Postfix cannot deliver any mails that are arriving (mailboxes not set up in the imapd), but instead lets them bounce. Postfix may be talking to the imapd, but gets an error response upon doing so.

My imapd.conf:

configdirectory: /var/lib/imap
partition-default: /var/spool/imap
# sievedir: /var/lib/sieve
admins: cyrus
allowanonymouslogin: no
allowplaintext: yes
autocreatequota: 10000

reject8bit: no
quotawarn: 90

poptimeout: 10
dracinterval: 0
drachost: localhost
sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN LOGIN
lmtp_overquota_perm_failure: no
lmtp_downcase_rcpt: yes
virtdomains: on
allowapop: 0
