dovecot - Nov 2005 - Setup help

I'd previously had dovecot running on a Debian server but recently 
migrated to Suse. The nice, simple setup for dovecot on debian is not as 
easy using the dovecot sources. My lack of experience I'm afraid! I'd 
like to continue to use dovecot, especially as my current maildir 
directories are all set up ready to be use again.

On suse (sles9) I have users authenticating by LDAP. In /var/log/dovecot 
I am getting errors like

dovecot: Oct 27 22:17:41 Warning: Killed with signal 2
dovecot: Oct 27 22:28:03 Error: auth(default): LDAP: 
ldap_simple_bind_s() failed (dn uid=dovecot,ou=people,dc=aro,dc=home): 
Protocol error

The errors also include the same LDAP error but with signal 11 or 15

I cannot get dovecot working. I've tried the 1.0 alpah and also found an 
earlier version on the suse 10 DVD. Basically I'm looking to use the 
IMAP server to centrally store emails on our home/business server. 
Previously we've been downloading mails (POP) from various mail accounts 
and moving them to dovecot (debian). In the future, I'd like to use 
fetchmail to do this part and locally deliver mail.

My LDAP domain base is dc=aro,dc=home. I generally use this as the local 
mail/DNS  domain as well. I have edited both /usr/local/etc/dovecot.conf 
and dovecot-ldap.conf. When I run dovecot it fails to start. I wonder if 
someone, in fairly broad ters could give me the steps for getting 
dovecot running with LDAP authenticated users?

what protocol version does your ldap server support? I've seen this
error when I used the wrong ldap version in dovecot-ldap.conf:

# LDAP protocol version to use. Likely 2 or 3.
ldap_version = 3

We are doing it exactly this way, here's our configuration:

------CUT------
hosts = artemis.bestsolution.at
dn = uid=the_dovecot_user,ou=daemon_user,dc=bestsolution,dc=at
dnpass = the_top_secret_password
ldap_version = 3
base = dc=bestsolution,dc=at
scope = subtree
user_attrs = uid,homeDirectory,MailMessageStore,,uidNumber,gidNumber
user_filter =
(&(objectClass=posixAccount)(accountStatus=active)(|(mail%u)(uid=%n)))
pass_attrs = uid,userPassword
pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n)))
------CUT------

Currently we are having some problems with dovecot's "POP3 meets
ldap"
implementation, but if you don't use POP3, you won't run into these.

happy hacking
