I thanks for the responses. However, I still don’t have a “vision” on how I can address my problem. My key points here are:

- Most of the enterprise companies have a directory service implemented already. So it does not make sense to create and maintain a second one just for SIP clients. With this in mind, we may use LDAP or RADIUS to prevent introducing a new directory just for SIP.

- As long as I understood from my readings (sorry if I am wrong), Kamailio LDAP will require a change on the customer’s LDAP schema, what most of the times is “undesirable” on large enterprise. So the way out is to use the native operation system RADIUS services from the customer’s environment, most of the time M$.

Sorry if I am bugging the community of a “carrier product” trying to adapt it to the enterprise environment. But why not? Kamailio is very stable, very low foot print, very scalable and it is a product that could become the “de facto” standard for “the SIP server” like we have a “de facto” standard for DNS, DHCP, SQL, HTTP, etc. in most of Linux distro. By other hand, most (or all) SIP-PBX servers out there will solve the SIP issues but will also interfere on the RTP, what Kamailio does not do...

So my next question is: is it there on the Kamailio community anyone willing to work on a “Kamailio Enterprise Edition”? I believe the enterprise market is just thousands times larger than the carrier one. So, does it worth to create a thread just to discuss using Kamailio on the enterprise? As the last question, am I on the right forum? I mean, am I asking the right thing on the wrong place?

Think about it: thousands and thousands of enterprise companies using Kamailio! Why not?

Cheers!

Yeah... I know it can be a kind of problem. But millions of companies are using MS meaning we need to "adapt" if willing to work for the enterprise market. If we do not offer some kind of integration with AD, then we will end-up having 2 user names and 2 passwords while the "good sense" is forwarding everyone to "single sign-on".

There is no need for two usernames, but could be the case for two passwords...

Anyway, it is tricky but M$ (I liked the $ thing here) can do MD5.

MD5 is just the hashing algorithm, with is used in www-digest authentication.

The issue here is not that someone hates M$, but it is that SIP phones implement only www-digest authentication mechanism, which requires to store the password in clear text or HA1 format (which is md5 over username, realm and password).

If you try to integrate with an existing system that stored the passwords in some shadow form, it is not just working. For each account you need to store the password in what www-digest can use for authentication.

I "would love" to see a "#!define WITH_RADIUS" at kakailio.cfg but we don't have it. However, as long as I understood, the RADIUS module is moving to obsolete as the AUTH module now also includes the RADIUS functionalities.

So, can you share any link where I can find some for dummies examples of using the current AUTH module to do RADIUS authentication?

As Juha pointed in another reply, you misunderstood, radius authentication has to be done using auth_radius module (there were two, only one was removed).

This tutorial is quite old, but still good for starting with:
- http://www.kamailio.org/docs/openser-radius-1.0.x.html

Hello,

it might not be possible if you don't have the digest authentication module in the radius server. Also, that means the passwords have to be stored in plain text or HA1 hash (md5 hash based on digest auth algorithm). Do you have these available in the M$ radius server?

Cheers,
Daniel

I am trying to integrate Kamailio as the SIP server for an enterprise company. The challenge is to authenticate the SIP users using the Microsoft RADIUS/AD so the users can use the same Windows user name and password on their PC softphone. As Microsoft has its own RADIUS server integrated with its Active Directory, has anyone has tried to use this kind of set up? Can you share docs, links, examples or whatsoever you think could help me? The only thing I am looking for is replacing the MySQL Kamailio authentication by RADIUS, nothing else.

Thanks,

Moacir
