[Dovecot] error in dovecot.log about ldap

[Antonio Casado Rodríguez]

Hi, i've upgrade dovecot 1.0.10 to 1.1.3 in Red Hat Enterprise Linux AS 
release 4

I've installed http://dl.atrpms.net/all/dovecot-1.1.3-0_80.src.rpm with 
http://www.rename-it.nl/dovecot/1.1/dovecot-1.1.3-managesieve-0.10.3.diff.gz 
patch.
And i've installed dovecot-sieve-1.1.5-8.el4.i386.rpm and 
dovecot-1.1-managesieve-0.10.3.tar.gz

I see in dovecot.log:
dovecot: Sep 19 12:20:56 Error: auth(default):
