Re: "double" realm problem

2009-10-30 Thread mr typo
solved it now another way:

   authorize {
auth_log
suffix
mschap
eap {
ok =  return
}
if ( ("%{User-Name}" !~ /@/) || ("%{User-Name}" =~ /@.*@/))
{
  update reply {
   Reply-Message := "FHSCommon: Wrong Username"
  }
  reject
}
}

maybe someone knows why the "failed to find module..." appears when using
policy.conf

Re: "double" realm problem

2009-10-28 Thread mr typo
when i put the "validate_username" direct after
server eduroam {
validate_username
authorize {
 .

i do not get an error. but it doesnt work. i am just trying around, i know
that the "validate_username" doesnt make sense when NOT in the authorize
section.

so anyone has an idea redgarding the "failed to find module..." problem?

thanks

hmm, interesting - this looks very much like a post i made here earlier
this month where 3rd-party virtual servers dont seem to pick up details from
main modules and include files - my case was that Autz-Type wasnt known if

In addition to my blackholing I now have added to my policy.conf file:

# only needs to be close enough to catch unroutable guff
validate_username {
if (User-Name !~ /@/ \
   || ( \
User-Name !~ /@.*@/ \
&& User-Name =~ 
/^[[:graph:]]*@([-[:alnum:]]+\.)+[[:alpha:]]{2,}$/ \
   ) \
) {
ok
}
else {
update reply {
Reply-Message := "Invalid User-Name Syntax"
}
reject
}
}


Then in your authorize section you just place 'validate_username' and it 
looks after everything for you.

What the above bumpf does is:
 * permit realmless (usernames without an '@') through, these are 
rejected later by matching against the NULL realm (*important*)
 * if there is an '@' in there then it
   * reject's if there are two or more '@'s
   * reject if the *realm* is not valid, for example the realm *must* 
be made up of at least two parts, and the end part must be at 
least two characters long

Hope that helps

Re: "double" realm problem

2009-10-27 Thread mr typo
i was trying to reject those "double" realm.
but i cannot find the right syntax and/or where to put the lines.

i was trying to put this lines in the user file:
DEFAULT User-Name =~ "/^...@company.com@.*/"
   Auth-Type := Reject


that did not work.
when putting:
if (User-Name ~= /^...@company.com@.*/) {
  reject
}
in the server configuration in authorize section, i get a strange error..

i am quite new with configuring freeradius, it would be nice if someone
could give me some real hint how to and where
reject those double @ @

thanks in advance.

Use some unlang in 'authorize' *before* you call 'suffix' that looks 
like:

if (User-Name ~= /^(@company.com)@.*/) {
User-Name := "%{1}"
}


As a side note, I currently have in proxy.conf:

# blackhole routing
realm myabc.com {
virtual_server  = auth-reject

nostrip
}
realm "~\\.3gppnetwork\\.org$" {
virtual_server  = auth-reject

nostrip
}


...and a virtual server:

server auth-reject {
authorize {
suffix

switch "%{Realm}" {
case "NULL" {
update reply {
Reply-Message := "No Realm"
}
}

# we should not get here
case "DEFAULT" {
update reply {
Reply-Message := "ERROR"
}
}

# we *really* should not get here
case "%{config:local.MY.realm}" {
update reply {
Reply-Message := "BIG ERROR"
}
}

case {  
update reply {
Reply-Message := "Realm Blackholed"
}
}
}

reject
}
}


I would recommend you reject straight away any double realmed users as 
you will only find yourself later on still having to deal with 
misconfigured kit; pain now means a *lot* less pain later down the road 
in my experience.

Any chance we are talking about eduroam? In this case: doing something
locally to make it work for these users even with misconfigured devices
is *not* going to do any good, and you will have helpdesk trouble as
soon as your users roam.

The rationale being straightforward: you "fix" your local realm
stripping, misconfigured clients are happy on your campus. Then they go
to other hotspots without your magic fixes, and roaming will break. At
some point they come back and whine, and you have to negotiate with the
remote side logs to figure their weird settings prevented them from
roaming. Then you still have to re-config the devices.

Not to mention that it damages the eduroam brand, since these people
will believe "roaming doesn't work".

Contrary to that, changing one setting once on those few(I guess - not
everyone on your campus uses Nokia cell phones, do they?) misconfigured
clients will fix the issue permanently and globally. I'm shepherding
about 1 end-users myself on an eduroam IdP setup, and a HOWTO for
Symbian which highlights neuralgic parts seems to work for me (at least
I don't drown in user requests, and still have time to read and write
freeradius-users :-) ).

as Stefan says - this looks suspiciously like Nokia Symbian clients.
if the client hasnt been configured correctly it will send the CN
of the certificate as the realm details...and other things - so you get
that double realm issue... which might get to you via external proxy..
or might not.

reject if you see more than one @ - or, if these are your people,
find them and fix their client. (in case of Nokia, its ensure that the
realm is specified rather than left to default setting.

Ah. Nokia cell phones with Symbian by any chance? Recent firmwares
behave less rude, but of course you may not have control over these clients.

A regex on the User-Name should do nicely. If it contains multiple @'s
Auth-Type := Reject.
