Order in authorize, does it matter?

[Beast]

I have sucessfully configure freeradius to use ldap and MSCHAP, however 
I just need a clarification on radius.conf.

Whether I put ldap before mschap or after, it seems did not change 
anything, at least output coming from debug log.
Does it matter?

in authenticate section, it does not matter wheter i put Auth-Type LDAP 
or not, which is correct, add LDAP or not?

----
authorize {
        preprocess
        #ldap
        mschap
        ldap
}
authenticate {
        Auth-Type MS-CHAP {
                mschap
        }
        #Auth-Type LDAP {
        #       ldap
        #}
}
