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:

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.

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?

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.
