I'm still banging my head against brick wall so comments on the following
would be appreciated.
No request-determined auth-type works for me right now, but one thing at a
time, so I've focused on MS-CHAP first.
This is a Redhat-7.3-i386 system with freeradius-0.8.1 and openldap-2.0.23.
FreeRadius was ./configured with the "Cistron alternative directories",
compiled and installed flawlessly.
The radiusd.conf file is as it comes from the "factory" with just the
following changes:-
basedn = "dc=BBD"
password = secret
server = "127.0.0.1"
identity = "cn=Manager,dc=BBD"
basedn = "dc=BBD"
filter = "(uid=%{User-Name})"
In the authorize section the LDAP was enabled. e.g:-
# The ldap module will set Auth-Type to LDAP if it has not already been set
ldap
}
Note that I haven't changed the order of the authz modules nor enabled LDAP
authentication.
The users file is factory-fresh with nothing added or altered.
As a test case I've used a MS-CHAP request which I apply via radclient(the
challenge & response attributes are a valid pair). In the following debug
trace it's my expectation that the MS-CHAP module would set the Auth-Type to
MS-CHAP, but obviously it doesn't. The only way I can get this to happen is
by providing the module with a valid smbpassword file, not something I want
do in the real world.
The following trace is from fire-up to doing one request:-
