DEFAULT entry in users file and LDAP, again

14 Dec 2007

      Sorry to bother you guys again:

a couple of weeks ago, I asked
...
...
With a users file like
DEFAULT
        User-Name = `%{User-Name}`
the server complains loudly about the missing Auth-Type when asking with
radtest
So how do I direct the server to use LDAP without setting Auth-Type?
Or is radtest somehow the wrong test tool in the new scenario??
Ivan advised me
...
Uncomment ldap in authorize and authenticate sections of radiusd.conf.
and it worked.
Now I'm going for a new production host and thought I'd simply copy
the working radiusd.conf (with minor adjustments, of course).
But again freeradius is unable to determine the proper auth-type. 
Static user entries and those with Auth-Type = System work fine.

In radiusd.conf I have:
modules {

        pap {
                auto_header = yes
        }

        chap {
                authtype = CHAP
        }

        pam {
                pam_auth = radiusd
        }

        unix {
                cache = no

                cache_reload = 600

                shadow = /etc/shadow

                radwtmp = ${logdir}/radwtmp
        }

        ldap ldap1 {
                server = "xxxxx.uni-marburg.de"
                identity = "uid=xxxxx,ou=xxxxx,o=Universitaet Marburg,c=DE"
                password = "xxxxx"
                basedn = "ou=people,ou=Staff,ou=Accounts,o=Universitaet Marburg,c=DE"
                filter = "(&(uid:caseExactMatch:=%{Stripped-User-Name:-%{User-Name}}) (!(UniMrDarfRadius=0)))"

                start_tls = yes
                tls_cacertdir           = /etc/ssl/certs
                tls_require_cert        = "demand"
                dictionary_mapping = ${raddbdir}/ldap.attrmap
                ldap_connections_number = 100
                #timeout: # seconds to wait for LDAP query to finish default: 20
                timeout = 60
                #timelimit: # of seconds server has to process the query (server-side
                #time limit) default: 20
                timelimit = 60
                #net_timeout: # of seconds to wait for response of the server (network
                #failures) default: 10
                net_timeout = 60
        }
[same for ldap2, ldap3]
[...]
} # end of modules
[...]
instantiate {
        ldap1
        ldap2
        ldap3
        eap
        mschap
}

authorize {
        preprocess
        chap
        mschap
        suffix
        eap
        files
          redundant {
            ldap1
            ldap2
            ldap3
          }
        pap
}

authenticate {
        Auth-Type PAP {
                pap
        }

        Auth-Type CHAP {
                chap
        }

        Auth-Type MS-CHAP {
                mschap
        }
        unix
        Auth-Type LDAP {
          redundant {
            ldap1
            ldap2
            ldap3
          }
        }

        eap
} #end of authenticate

The debug output shows a successfull LDAP dialog about authorization, 
but then no Auth-Type is found:
