SSO not quite working

I am trying to get SSO working. In debug I get this error when trying to loging afterfollowing the SSO wiki. Everything checks out ok but obviosly missed something simple, any ideas

CLients used spark 2.5.7 and pandion

Neither work

Thanks for you help in advance

I would question the validity of your keytab. I would recommend simplifying the name of that file for one. Try using this code:

ktpass -princ xmpp/SHS.WILTS.SCH.UK@SHS.WILTS.SCH.UK -mapuser UserName -pass XXXXXXXXXX -out jabber.keytab

Replace UserName with the username of an LDAP user you want to associate the keytab.

The wiki is deprecated. Get the current documentation at SSO Configuration. Also, to view the keytab on a Linux/Unix system, use the klist command like this:

klist -kt /opt/openfire/conf/xmpp-comms.new.keytab

Also, the error you are showing I do not think has anything to do with SSO. If you turn SSO off (and change nothing else) does it work?

Hi, I’m also having a similar problem with SSO. I’ve configured everything as required and have used the Smack Debug tool in Spark to see what’s happening.

During a login, it appears that two packets are sent out. One is a get packet with the payload:

<iq id=“1eBcD-5” type=“get”>

<query xmlns=“jabber:iq:auth”>




The second sent packet is a set packet with the payload:

<iq id=“1eBcD-6” type=“set”>

<query xmlns=“jabber:iq:auth”>






Following this, two packets are received, the first a result packet which contains:

<iq id=“1eBcD-5” type=“result”>

<query xmlns=“jabber:iq:auth”>






Which is followed by the final packet, which is an error packet containing:

<iq id=“1eBcD-6” to=“jabber-server.local/f3f5f209” type=“error”>

<query xmlns=“jabber:iq:auth”>





<error code=“401” type=“AUTH”>

<not-authorized xmlns=“urn:ietf:params:xml:ns:xmpp-stanzas”/>



Anyone got any suggestions? I’m at a loss as to what’s going wrong here.

Any help gratefully received.


Try this new FAQ for setting up SSO with Openfire. It’s what worked for me after everything else failed so I documented it for others.

HOWTO: SSO Configuration for Windows (Server and Clients) and Mac Clients

Let me know if this helps.



Thanks for your suggestion - I’ll follow your advice and let you know how I


Kind regards,
