It's been a while since I was working on this, and I've made some
further progress but FreeRADIUS is still not doing what I'm after. It is
successfully sending back an Access-Accept packet or Access-Reject
packet as I would like, but none of the reply attributes that correspond
to the group that they are a member of are returned. Initially I didn't
have FreeRADIUS configured correctly (nothing in the "users" file to set
a User-Profile...), now from what I can gather, the rlm_ldap module is
now doing a search for the correct profile, but the filter it is using
is incorrect and I can't work out where you would change it in the
configuration file.
Please take a look at the line in my debug output that shows the ldap
search for the user profile - the filter doesn't look right to me. I
want it to use the filter being the Ldap-Group...I don't think anywhere
in my config though I can set what that filter is!?
rlm_ldap: performing search in
cn=dialup,cn=group,cn=radius,cn=config,ou=eaccounts,dc=megashaft,dc=com,
dc=au, with filter (objectclass=radiusprofile)
Anyway I'll include the rest of the debugging below - I might be miles
off...
Here is what I have added since last time in my users file (this is all
that is in there at this stage - the nas terminates both adsl and dialup
so I'll have different profiles eventually for each type, but for the
moment I'm just using the dialup example...
--- users file ---
DEFAULT Ldap-Group == dialup, User-Profile :=
"cn=dialup,cn=group,cn=radius,cn=config,ou=eaccounts,dc=megashaft,dc=com
,dc=au"
Fall-Through = no
This is the ldap section of my radius.conf file
-- radius.conf ---

# and sample authorize{} and authenticate{} blocks

server = "ldap2-dev.megashaft.com.au"
identity = "cn=root,dc=megashaft,dc=com,dc=au"
password = testpassword

# filter = "(uid=%{Stripped-User-Name:-%{User-Name}})"
filter =

"

groupmembership_attribute = radiusGroupName

}
In the authorise block I have
authorize {
preprocess

mschap
ldap
}
And in the authenticate block I have
authenticate {
Auth-Type PAP {
pap
}
Auth-Type CHAP {
chap
}
Auth-Type MS-CHAP {

Auth-Type LDAP {
ldap

}

Thanks for any suggestions you may have! - I've gotten a lot further
from reading that document at http://doris.name/radius/ - that was what
gave away the tip of needing to use the users file!
Cheers,

Check out www.doris.cc/radius. It is my setup that I am using and does
what you would want. If you have any questions, post to the list and
I'll try to answer them as best as I can.
