Of course it is useful, thanks to kerberos users don't have to type
their password every time, or worst save it in a text file in their home
Pidgin does support GSSAPI auth, Empathy sadly doesn't.
On the server side I have successfully configured jabberd2 and Openfire.
The first steps are the same for both jabberd and openfire:
1) Set up your DNS, creating the proper _xmpp-client._tcp and
_xmpp-server entries. For example
ipa dnsrecord-add mydomain.com _xmpp-client._tcp --srv-rec="10 100 5222
2) Create and export the keytab for the server. Preferably your jabber
server should join the ipa domain so you don't have to set up kerberos
and ntp manually, the proper fqdn hostname, etc.
on-ipa-server# ipa service-add xmpp/jabberserver.mydomain.com
on-jabberserver# ipa-getkeytab -s ipa-server -p xmpp/jabberserver.mydomain.com
Next for jabberd2:
1) Edit /etc/jabberd/c2s.xml and enable the sasl methods in the
2) Edit /etc/sasl2/xmpp.conf (or /usr/lib/sasl2/xmpp.conf depending on
your installed OS)
mech_list: GSSAPI PLAIN
3) chown /etc/krb5-xmpp.keytab so your jabberd service can access it.
1) Edit /opt/openfire/conf/gss.conf
2) Edit the <sasl/> and <ldap/> sections
3) In the openfire web setup you should set up the ldap connection
making sure the app can see all of your ipa users and groups. After this
you should enter into the web administration and add some system
sasl.gssapi.config = /opt/openfire/conf/gss.conf
sasl.mechs = GSSAPI PLAIN
sasl.gssapi.useSubjectCredsOnly = false
xmpp.domain = mydomain.com
xmpp.fqdn = jabberserver.mydomain.com
4) chown /etc/krb5-xmpp.keytab so your openfire service can access it.
Hope this helps!
