some users not authenticating

[Tony Spencer]

I've got, well think I have, radius to accept all logins no matter what
password they send.

However some users still cannot login, its around 10 users out of 200.

I'll show details for one user that can login ok and one user that can't.

I'm guessing it's something the end user is doing because they all come in
via the same NAS and have exactly the same radius entry.

If I can get around this by just accepting anything that would be ideal,
since our realm is the only radius logins that are sent to us.

 

Here is a user that can't login:

 

##

Thu Mar  2 09:59:03 2006 : Auth: Login incorrect (rlm_chap: Clear text
password not available): [user22 at dsl.realm.com/<CHAP-Password>] (from client
l2tp port 510)

##

 

Here is someone that did authenticate ok:

 

##

Thu Mar  2 09:55:26 2006 : Auth: Login OK:
[user3 at dsl.realm.com/<CHAP-Password>] (from client l2tp port 492)

##

 

My users file has:

 

##

DEFAULT Auth-Type = Accept

##

 

And the entries for both users above are identical apart from the username
and IP assignment:

 

##

user3 at dsl.realm.com      Auth-Type := Accept

        Service-Type = Framed-User,

        Framed-Protocol = PPP,

        Framed-Address = 192.168.0.1,

        Framed-Netmask = 255.255.255.255,

        Framed-Compression = Van-Jacobsen-TCP-IP,

 

user22 at dsl.realm.com      Auth-Type := Accept

        Service-Type = Framed-User,

        Framed-Protocol = PPP,

        Framed-Address = 192.168.0.2,

        Framed-Netmask = 255.255.255.255,

        Framed-Compression = Van-Jacobsen-TCP-IP,

##

 

 

Here is some radius debug first for the user that can't login:

 

##

        Framed-Protocol = PPP

I can see that it seems user33 is sending a blank white space before his
username, but I don't see that this would make a difference since I'm
accepting everything anyway. And from the command line I can use "radtest"
and send blank spaces and it works fine. Although I do see that the user
would not get assigned his IP address. But first I'd like to ensure everyone
can authenticate.

 

Any idea?

Thanks in advance

Tony
