dovecot - Feb 2012 - Multiple userdb possible?

Hello,

I am running v2.0.13. In my dovecot.conf I have:

userdb {
   args = /etc/dovecot/dovecot-usrdb-ldap.conf
   driver = ldap
}

passdb {
   args = /etc/dovecot/dovecot-passdb-ldap.conf
   driver = ldap
}

Is it legitimate to include multiple ldap userdb's, like:

userdb {
   args = /etc/dovecot/dovecot-usrdb-ldap1.conf
   driver = ldap
}

passdb {
   args = /etc/dovecot/dovecot-passdb-ldap1.conf
   driver = ldap
}

userdb {
   args = /etc/dovecot/dovecot-usrdb-ldap2.conf
   driver = ldap
}

passdb {
   args = /etc/dovecot/dovecot-passdb-ldap2.conf
   driver = ldap
}

If it is legitimate (in case configuration is different, please correct 
me), in which sequence userdb's are evaluated?

Thanks,
Nick

Of course. The driver chosen is not significant; the query used is 
all that matters. Having two LDAP searches is conceptually no 
different than having system users and SQL users.

In the order specified. A /etc/dovecot/dovecot-usrdb-ldap1.conf match 
prevents searching in /etc/dovecot/dovecot-usrdb-ldap2.conf; keep 
this in mind in setting up the queries.

Thank you for the clarifications!
