[Freeswitch-users] LDAP

Hi Nick,

FS may be able to talk directly to LDAP for what you want to do.

There is a ³mod_xml_ldap
k=1> ² although I have not been able to find much documentation for it.

I see in ³src/mod/xml_int/mod_xml_ldap² there is an example LDAP schema
"fsv2.schema² and the aptly named ³reallyconfusingslapcat².
>From these examples, it looks like the approach was to mirror the XML
structure you need to return in the LDAP directory.
So its looks built for flexibility but could be much more than what you want
to deal with.

Building a CURL<->LDAP GW may be cleaner and easier and will allow you to
use your existing LDAP, perhaps just having to add a few attributes.

I also found the following quite old post
(http://article.gmane.org/gmane.comp.telephony.freeswitch.user/6974) on some
other forum. 
Not sure if the module has been updated since and if/how much the below
needs to change, but maybe it still works.
Copying it in below for the sake of completeness.

Be advised mod_xml_ldap is probably not production quality and will
undoubtedly change, eventually at least.

Here is what I used once:


    <binding name="directory">
		<!--%s is populated with the extension -->
		<param name="filter" value="(FSid=%s)" bindings="directory"/>
		<!--basedn for the searches %s is replaced with domain-->
		<param name="basedn" value="ou=people,dc=example" />
		<param name="url" value="ldap://" />
		<param name="binddn" value="cn=admin,dc=example" />
		<param name="bindpass" value="secret" />

			<!-- we need to translate these attrs into FS attrs -->
			<tran name="id" mapfrom="FSid" />
			<tran name="mailbox" mapfrom="FSmailbox" />
			<tran name="password" mapfrom="FSPassword" />
			<tran name="vm-password" mapfrom="FSvm-password" />
			<tran name="email-addr" mapfrom="FSemail-addr" />
			<tran name="vm-email-all-messages" mapfrom="FSvm-email-all-messages" />
			<tran name="vm-delete-file" mapfrom="FSvm-delete-file" />
			<tran name="vm-attach-file" mapfrom="FSvm-attach-file" />

    <binding name="configuration">
        <param name="filter" value="(%s=%s)" bindings="configuration"/>
        <param name="basedn" value="name=%s,dc=example" />
        <param name="url" value="ldap://" />
        <param name="binddn" value="cn=admin,dc=example" />
        <param name="bindpass" value="secret" />

which should/probably/might work with ldap objects like these:

dn: cn=John Skopis,ou=people,dc=example
objectClass: person
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: FreeSWITCH-Exten-Object
objectClass: top
cn: John Skopis
sn: Skopis
givenName: John
FSid: 1001
FSmailbox: 1001
FSpassword: 1234
FSvm-password: 1001
FSemail-addr: john+fs at ...
FSvm-email-all-messages: TRUE
FSvm-delete-file: TRUE
FSvm-attach-file: TRUE

dn: SIPIdentityUserName=1001,ou=h350,dc=example
objectClass: person
objectClass: SIPIdentity
objectClass: top
cn: 1001
sn: 1001
SIPIdentitySIPURI: sip:1001 at ...
SIPIdentityPassword: 1234
SIPIdentityUserName: 1001
SIPIdentityServiceLevel: premium


The ³trans² part looks very useful.

>From the code I can see that the module supports exactly the following

/* Params */
/* Variables */

I hope this helps.

If you get this working, please let us all know how you did it here ­ and
make sure the wiki gets updated.

Best Regards

Good day to you.
Could you advise me how i can implement auth users via LDAP in the simplest
Do i have to write my own application for mod_xml_curl(maybe there is such
application somewhere)?
Or i can use the mod for freeswitch and it will work like a charm.(i use
both sip and skinny users)
Thank you for your time,
Best Regards
Nick Zaitsev
