I rebuilt the hashes against domain.com and then tried to connect to
sip1.domain.com and sip2.domain.com and sip3.domain.com with all of
the having
# ----- auth_db params -----
#!ifdef WITH_AUTH
modparam("auth_db", "db_url", DBURL)
modparam("auth_db", "calculate_ha1", 0 )
modparam("auth_db", "password_column", "ha1")
modparam("auth_db", "load_credentials", "")
modparam("auth_db", "use_domain", MULTIDOMAIN)
And in the routing process :
if (!www_authorize("domain.com", "subscriber"))
{
www_challenge("domain.com", "0");
exit;
}
+++++++++++++
My point is that the hashes are caculated from user:doman:pwd which
are extracted from the SIP packet and in this case the domains are
sip1,sip2,sip3 while the hashes stored in the database are generated
against domain.com
If " ha1 is actually hash over 'user:realm:pwd' " shouldn't I have to
set the domain/realm in the config file ?
the first parameter in www_authorize and www_challenge functions is the
realm and it is used to build the digest response.
Is your phone putting user@domain in authorization header? Can you paste
here the ngrep of registration?
Cheers,
Daniel
I might be wrong....thanks for the help so far.

Hi Daniel
This certainly makes sense, I will try it in a few mins, but what I
observed at Debug Level 3 is that Hash is calculated before
www_authenticate is executed and it shows HA comparison failed, if I
do use domain.com instead of $fd and use $domain.com in db domain
field and build HA1 filed based on that, wont Kamailio still try to
build the HA1 hash which it will compare form user:domain:pwd where
domain is fed in to the hash function from the header of the SIP
packet ?
the ha1 is actually hash over 'user:realm:pwd' -- it is just common practice
to use the domain as realm, since realm should be a unique token to identify
the service, but it can be any random string. realm is given as parameter
to auth functions in kamailio.cfg

Daniel

Hello,
you can simply use 'domain.com' as realm parameter to authentication
function instead of $fd. Also build ha1 and ha1b with domain.com and then
you are safe no matter which sip server is used.
Of course you can build the realm by striping first token before '.' in
$fd
and pass it to authentication functions, but not sure if makes sense
since
it should be always domain.com
Cheers,
Daniel

Hi
After some research it seems to me that the only way to achieve this
is to "try" and change how hashing is done in the source code, a
little bit too ambitious for me, and it means I will have loads of
problems each time an upgrade is released.
Or
Use pseudovariables to fix the value of the $fd value to something
constant, while this worked for values like $var(y) I was not able to
assign/strip $fd to remove the subdomain part.
Any input please ?

Hi
I do have 3 Kamailio servers, one for mobile phone registrations, one
for softphone registrations and one for SIP device registrations. Each
of those devices connects to it's perspective kamailio server
sip1.domain.com
sip2.domain.com
sip3.domain.com
All 3 Kamailio servers share the same database, and users can use
their kamailio user/pwd on any of the devices, now I want to use
encrypted passwords and remove clear text passwords from the database.
I did test with one server and all is fine,however if a user want to
register from the second kamailio server it does not work, basically
because the db domain entry from which the hash is created is
sip1.domain.com and stored in the db, while the user connects from to
sip2.domain.com this eventually generates a different hash.
Is there anyway to overcome this ? Can I exclude Domain from Hash
generation ? Any other option that allows me to do the above ?
Thanks
