Sorry, just saw a mistake in the test command I
posted - correction below..
Hi,
I have a requirement for
'authentication' via LDAP. Only a User-Name is passed to freeradius.
The requirement is to perform an LDAP lookup, and
if the user exists, return a couple of other values in the LDAP database for
that user.
If the user does not exist, reject.
I have the LDAP lookups working, but I cannot
figure out how to tell freeradius to skip the password check
(authorization?).
I am using radcleint to test this via,
**** The correct test command for the debug below
was
echo "User-Name=SomeUser" |
/usr/local/bin/radclient -s 127.0.0.1 auth testing123
Below is a debug of this test.
