[Dovecot] ldap userdb warning in v2.1.1

[Nikolaos Milas]

Hi,

I've upgraded from 2.0.13 to 2.1.1 and when I started the service, I got 
the following warning:

Mar 21 10:07:23 imapserver dovecot: master: Dovecot v2.1.1 starting up 
(core dumps disabled)
Mar 21 10:08:17 imapserverdovecot: auth: Warning: ldap: Ignoring changed 
user_attrs in /etc/dovecot/dovecot-passdb-ldap.conf, because userdb ldap 
not used. (If this is intentional, set userdb_warning_disable=yes)

I didn't see such warnings in 2.0.13.

I guess I should/could remove the "user_attrs" line from 
dovecot-passdb-ldap.conf because it's not needed? (I could also set 
"userdb_warning_disable=yes" as advised, but I'm trying to figure out 
what's the real cause of the warning.)

The config follows below.

Thanks,
Nick
