Yes.

Mailbox format is Maildir. I haven't disabled index files, at least not
knowingly. Basically I'm using a default configuration, based on
whats delivered with the Debian snapshot package of dovecot2
(from what I can tell, this is doc/example-config/* in the source
tarball) with the neccessary changes to authenticate against a LDAP
server.
However, from a look at the maildirs I cannot find a main index file as
described in [1], only the two other indexes.

<hostname>:/var/spool/mail1/test2/Maildir# ls -l *index*
-rw------- 1 vmail root 17408 21. Jan 21:12 dovecot.index.cache
-rw------- 1 vmail root  2080 21. Jan 21:12 dovecot.index.log

Is that normal?

In my current setup its reproducible.
Note: This is dovecot 2.0 on Debian Lenny.
