use of pam and sql db simultaneously

[Markus Krause]

hello list,

i would like to authenticate users via pam and sql.

part of my radiusd.conf (freeradius 1.0.5 on sles 9) is:
+++++ part of radiusd.conf
instantiate {
}

authorize {
        preprocess
        files
        sql
        shorttermaccount
}

authenticate {
        pam
}

preacct {
        preprocess
        acct_unique
        files
}

accounting {
        detail
        radutmp
        sql
}
------- part of radiusd.conf

if i have the following line in /etc/raddb/users:
++++++ users
Auth-Type = PAM
    Fail-Through = Yes
------ users

users known by pam get access-accept, but those in sql don't, the debug output
says:
++++++ radiusd -XA

Listening on accounting *:1813

----- radiusd -XA

if i delete the line "DEFAULT Auth-Type = Pam" (and Fall-Through = Yes) the
users in sql get an access-accept answer.

what am i doing wrong here?
do theses modules (rlm_pam and rlm_sql) exclude each other?
how can i use them simultaneously i.e. in parallel?

thanks in advance for any hints!

and merry x-mas everyone! :-)

  regards,
    markus
